The show is adapted from a popular novel of the same name and tells the story of an unstoppable reporter and a homicide detective who work closely together to track down a series of murders.The cooperation between the two gradually deepened, and they were involved in a huge whirlpool. They not only faced brutal murders, but also faced complex love entanglements.

The reporter's intelligence and keen insight make her an expert at catching the bad guys by the collar. She can always find the key clues from various clues.With his professional knowledge and experience, the criminal police officer of the serious crime team is able to put handcuffs on the bad guys and bring them to justice.The cooperation between the two made them an invincible partner. Together they overcame seemingly unsolvable mysteries and upheld justice.

However, with the in-depth investigation of the case, the two gradually fell into a more complicated situation.They discovered that there was a larger and more dangerous conspiracy hidden behind this series of murders, and the whole city fell into panic.In the process of tracking the truth, their lives also face huge threats.

During the intense investigation process, the relationship between the two also quietly heated up.They not only have to deal with complicated cases, but also face the entangled love entanglements between them.Their hearts waver between danger and desire, and they have to find a balance in the confusing plot.

Seo Jung-won was spying on a congressman when she broke into a restaurant and confronted the congressmen and reporters who were dining.She accused lawmakers of paying reporters to write specific articles, while her videographers recorded everything.Later, she aired the same content on her own show - Grab your collar.

Zhenyuan was called to see her boss.The previous reporter Noh Ji-ho and Jung-won worked for the same company, and the two had been arguing for some time.Zhenyuan's boss told her that the host of -Grab your collar- would be replaced soon, but she claimed that the show belonged to her, not the company.

Meanwhile, Representative Mok is angry about the broadcast and seems to be planning to seek revenge on Jeong-won.At this time, a police chase was underway.A police detective named Kim Tae-hun catches the criminal and even saves a hostage in the process.Back in the office, Tae-heon sees a clip from Jung-won's show and it's obvious she's important to him.

Jung-won talks to a mysterious figure on the phone, who is sitting next to a set of screens and has been feeding her information about Assemblyman Mok.Jeong-won then met her husband Seol Woo-jae.They meet Woo-jae's father, who is unhappy with Jung-won's job because Assemblyman Mok is his friend.

Woo-jae defends Jeong-won, and we learn that his father only accepted the marriage because of Woo-jae's insistence.Back home, Woo Jae gave Zhen Yuan a necklace to celebrate the third anniversary of Grab your collar.

At work the next day, Zhenyuan investigated a man named Li Yizhen.They then watched Congressman Mo's press conference, where Congressman Mo appeared to be contrite.Zhenyuan goes to the police station.In the bathroom, she met an actress named Cha Eun-chae.She is a fan of Zhenyuan and said that her boyfriend is a writer, just like Zhenyuan's husband.She took a selfie with Zhenyuan.

Later, Zhenyuan received the GPS location of Li Yizhen's spare mobile phone and headed there.Her contacts guided her, but she hit a dead end.Above her, a badly injured woman hung half out of the window.Zhenyuan was shocked when she saw it and rushed upstairs to find that the man was dead.Zhenyuan managed to call the police.

Tae-hun and his partner arrive and take Jung-won to the police station, where she explains her situation.The victim turned out to be Congressman Mok’s housekeeper Kim Myung-sook.The politician himself arrives and accuses Jeong-won of murder.

At home, Zhenyuan took out her laptop and mouse from the safe and started typing events.When she found her hands covered in blood, she decided to take a shower first.That night, Woo-jae finds Jung-won standing on the balcony and comforts her.The next morning, Tae-heon and his partner visit Kim Myung-sook's house.They found a newspaper clipping about Congressman Mok.But they didn't find her phone.

Jeong-won visits a therapist, who tries to get Jeong-won to open up about her past.But Zhenyuan saw an article written by Lu Zhihao, accusing Zhenyuan of polluting the scene.She argued with him at work and left.She received numerous text messages, including one saying she should expose her husband before exposing others.Woo-jae later takes Jung-won to her late father's resting place, saying it will bring some comfort.

A month later Zhenyuan received a text message similar to the one before, blaming her husband.Later in her therapy appointment, Jung-won recalls her father, who is also an investigative reporter and has won an award for his work.Two months later, he died.Jeong-won then describes how, as a young girl, she found her father murdered in her home one night.The killer has still not been caught.

At work, Jeong-won and her team learn that another reporter, Hae-joon, has been arrested for taking bribes.Afterwards, Cha Eun-chai called Zhenyuan and invited her to her home.Zhenyuan thought this was big news and went.

In her apartment, Jung-won sees Eun-chae wearing the same necklace she gave to Woo-jae.She also has Woo Jae’s books on her bookshelf.Suddenly, Eun-chae says that she and Woo-jae are dating.She hinted that they have been together for a year.Those mysterious text messages were also sent by Eun Chae.

Zhenyuan argued with her and stormed out.Eun-chae follows her and shows her an ultrasound photo, saying she is three months pregnant.Jeong-won tells her to leave, but when she steps into the elevator, she becomes uneasy.

Jeong-won goes to the police station and meets Tae-heon, who realizes she's distracted.He drove her home and then got out of the car to get her medicine.Jung-won gets a call from her husband Woo-jae and pretends everything is fine.He said he had to work overtime.

At home, Jeong-won sees the decorations she put up to celebrate the anniversary of her husband's first novel, then sighs and sleeps on the sofa.The next day, she follows Woo-jae, who goes to a marriage counseling clinic.

Jung-won meets with her team to interview an informant.When they realize she doesn't look well, Jeong-won decides to leave.She went to see her therapist, and a text message directed her to the clinic's new location.Jung-won reaches the building and walks to the mentioned location, but there is no clinic there.Instead, she saw a woman lying in a pool of blood, who was Cha Eun-cai.

When Zhenyuan was about to call the emergency call, she received a call from her boss Jiang Inhan.He told her that he had recommended her to be the anchor of the 9 o'clock news and warned her not to get into trouble.

Jung-won hangs up the phone, takes a photo of Eun-chae's body, and runs down the stairs.There, she bumped into a staff member at the therapist's clinic, who admitted she had given the wrong floor number.Zhenyuan participated in the treatment as usual, hiding the blood on her sleeves.

As she was leaving, Zhenyuan noticed that there were no cameras in the building called Leaders Palace.Back home, she washed her shirt sleeves and blamed herself for running away.Woo-jae came home drunk, claiming he was stressed because he couldn't write anything.

Tae Heon is called in to investigate Eun Chae's murder.He and his partner Myung-soo find Eun-chae stabbed in the abdomen.They also found a broken chain in her hand, without the pendant.This building turned out to be the home of Eun Chae’s new agency.Tae-heon also notices a clock without a battery, similar to the clock in Kim Myung-sook's home.

The next morning, Woo-jae wakes up and finds Jung-won in a bad mood.He thought it was because he had been drunk the night before.When news of Eun-cai's death spread, Zhenyuan's boss asked her to report Eun-cai's story on the show.She checked the surveillance footage around the building and then called her anonymous contact Zeus to get information on people who had been there.

Tae-heon visited the forensic doctor, who told him that Eun-chae's injuries were almost identical to Kim Myung-sook's.He also learns that Eun-chae is three months pregnant.He returns to the police station to find Jung-won waiting for him.She asks him about the time of death and Eun-chae’s pregnancy, and gets confirmation from him.

Jung-won returns home and confronts her husband about the ultrasound photo Eun-chae gave her.Woo-jae admits that Eun-chae has been pursuing him, but they only met once, at a publishing event.He even blocked her phone number.

When she asked him why he went to a marriage counseling clinic, he said he went to a psychiatrist because he had been diagnosed with depression.The next morning, Jung-won can’t find the necklace Woo-jae gave her.She then talks about Woo-jae's loneliness and promises to spend more time with him.

Zhenyuan still can't find the necklace at the company.She learns that Noh Ji-ho may be covering up Eun-chae's murder and uses the confidential information she has to get In-han to hand the case back to her.Later, Jung-won interviews a marriage fraud victim.She discovers her husband's second cell phone and realizes his entire identity is fake.Deep down, Jung-won connected the story to Woo-jae's actions.

Tae Heon visited Eun Chae's brother and got the password to Eun Chae's apartment.In the apartment, Tae-heon notices several novels written by Woo-jae.He also found a cake in the refrigerator.Myung Soo checked the apartment video and discovered that it was Jeong Won who gave Eun Chae the cake.At work, Jeong-won called Zeus and asked him to investigate whether Woo-jae had another phone number.

Tae Heon spotted Jeong Won in the video outside Leaders Palace and went to meet the reporter.Zhenyuan answered all his questions, but she was at a loss when Taeheon asked about the envelope Eunchae gave her and the reason why Zhenyuan was slapped.Jung-won said it was a personal matter and explained her treatment process at Leaders Palace.But Tae-heon guessed the extramarital affair correctly.They argue and Tae-heon returns Jung-won a pen with her name on it.Zhenyuan threw it into the trash can.

A flashback scene shows Jung-won pestering Tae-heon for his phone number so she can contact him.As he wrote the number with her pen, she made a joke that they were both single and would eventually date.

At home, Jeong-won took Woo-jae’s phone while he was sleeping and unlocked it.But she found no hard evidence.The next morning, the couple was called to see Woo-jae's father, Seol Pan-ho.But Councilor Mou also appeared, bringing an unexpected surprise.Panhao asked Zhenyuan to apologize, but she politely refused.

Representative Mou hinted that he knew Jeong-won’s father, Seo Sang-kyun.As everyone is leaving, Councilor Mou comments that Zhenyuan married the wrong person.On the way home, Representative Moo received a call from Tae-heon asking why Kim Myung-sook withdrew her salary within a day of receiving it.

Tae-heon and Myung-soo then visited the psychiatric clinic and found that Jeong-won entered the clinic at 7:45.15 minutes after she entered the building.The detectives then interview Eun-chae’s brother Jin-se.He asked Jin Shi why he drove into the basement of Leaders Palace.Jinshi claimed he just parked his car there and rode off on his bicycle.Tae-heon reveals the pregnancy and asks more questions, but Jin-se is clueless.

Zeus calls Jung-won and tells her that Woo-jae has the phone number of a one-man publishing company registered in his name.He gives Jeong-won her number but is unable to trace her location.

Jeong-won couldn't find it at home, but she eventually found the phone in a garbage bag in the trash.However, the phone seemed to have been wiped of data, so Jeong-won took it to a store where the data could be restored.

Tae Heon and Myung Soo meet with Eun Chae’s manager.She does think Eun-chae is dating someone, but doesn't know who.She also claimed that Jin Se used to look through Eun Chae's phone and take money from her.He even threatened her with a knife once.

Tae-heon returns to the police station to discuss the case with his boss.He mentions a police detective in Cha, and we see a picture of him and another detective on Tae-heon’s desk.Myung Soo walks in and shows Tae Heon the record of Eun Chae calling the number listed in Woo Jae’s company.

Meanwhile, Zhenyuan and her team enter the home of a marriage fraud victim with her team and cameraman.They catch the husband assaulting his wife, and when she tries to stop him, he hits Jung-won too.Tae Heon arrives just in time, pulls him away and arrests him.

Back at the police station, Tae-heon scolds Jeong-won for not being careful enough.He recalls how his partner, Detective Cha, died because he let his guard down.

At home, Zhenyuan received a list of people who had been to Leaders Palace from Zeus.She realizes that Woo-jae went there on the day Eun-chae died.Woo Jae comes and Jung Won asks him why he was there that day.Before he can answer, Tae-heon arrives and tells Woo-jae to go to the police station with him.

In the past, Woo Jae and Jung Won walked into a theater hand in hand, and the musicians on the stage played the melody of love for the two.Zhenyuan did not want the tediousness of a traditional wedding, so she arranged this unique event.The two exchanged rings and made vows, and the atmosphere was extremely romantic.

Back to the present, when Zhenyuan questioned Woo-jae, Tae-heon hurriedly arrived and told Woo-jae that he needed to go to the police station.In the police station, Tae-heon mentioned the plot in Woo-jae's novel where a woman was stabbed in the abdomen and died.Regarding Eun-chae, Woo-jae claimed that he was being followed. The reason he went to Leaders Palace was just to buy Chinese food. He knew nothing about Eun-chae's agency, but he was accidentally involved in her sponsorship.He even agreed to take a DNA test.

Woo-jae's mind drifts back to the last phone call with Eun-chae, where she revealed some secrets, but the details remain a mystery.At Jung-won’s workplace, a colleague mentions a rumor that Assemblyman Mok is Eun-chae’s sponsor.Woo Jae came to explain the misunderstanding between the Chinese restaurant and the phone, but was interrupted by Zhen Yuan's boss and had no choice but to leave.

In the police station, Tae Heon still doubts Woo Jae.Meanwhile, Myung-soo discovers that Eun-chae’s bank account is almost empty and no evidence of her sponsors is anywhere.Zhenyuan tried to contact Cha Jinshi for an interview, but was rudely rejected.Tae Heon arrived and together with Jeong Won questioned Jin Se with evidence, such as the fact that he threatened Eun Chae with a knife.Jin Shi angrily revealed that Eun Cai was ready to retire and knew that his life was not long.On the way home, Jin Shi called Representative Mo.

Zhenyuan retrieved the secret mobile phone left in the store, but was told that the data could not be recovered.She and Woo-jae go to the police station again, and Tae-heon reveals that the DNA samples don't match.Back home, Zhenyuan asked Woozai about the second mobile phone.Woo-jae explains that he keeps it with him but doesn’t think it’s important enough to tell Jeong-won.Instead he believed someone was setting them up.

Later, Jung-won talks to the staff at the therapist's clinic, and the woman who sent the wrong number claims to have sent the correct number but is confused as to why the mistake occurred.At this time, the relationship between Eun Chae and Woo Jae was exposed, and the accompanying photos became irrefutable evidence.Jung-won realizes that the person who repaired Woo-jae’s phone leaked the information.Zeus provides the man's location, and Tae-heon follows Jeong-won to the store.

Woo-jae's father questions whether his son committed the crime, implying that he has reason to believe it.Woo Jae angrily denied it and ran away from home but was surrounded by reporters.Zhenyuan found the key person in an Internet cafe and chased him. Finally, Tae-heon subdued him.He admits to selling the photos to reporters and reveals that Woo-jae tracked the phone, gave him money to destroy evidence and lied to Jung-won.Zhenyuan saw the intimate video and finally became convinced of her husband's affair.

Woo-jae calls and insists that someone is setting them up.Zhenyuan sneered and hung up, then watched Woo-jae's response to the reporter.He said he only loved his wife and would love her forever.However, the next scene shows Woo-jae killing Eun-chae, and the truth remains unclear.

Tae Heon approaches Woo Jae and reveals key information about the video.As Tae Heon was about to leave, Woo Jae stopped him and provided a key alibi.Back home, Zhenyuan vents her emotions to Woo-jae, while Woo-jae admits that she feels lonely and longs for more love.Jeong-won defends herself, insisting it's not her fault, and she also sees Woo-jae as the main suspect.

Meanwhile, Tae-heon and Myung-soo start digging into Woo-jae's alibi.They track down a security camera footage that shows Woo-jae fighting with a waiter at a cafe.Unexpectedly, the owner of this cafe is actually the daughter of Congressman Mo Hengze, named Mo Xiulin.

In search of a moment of tranquility, Zhenyuan chose to stay in a hotel.Woo Jae went to another apartment, and Jin Shi followed.It turns out that Jin Shi knows the password because Eun Chae once told him.Jin Shi tried to blackmail Yu Zai, but was overpowered by the latter.Woo-jae holds a photo of Eun-chae's injuries due to Jin-se's abuse, and uses this as a threat.

While investigating another cell phone video of Woo-jae, Tae-hyun accidentally discovered that Woo-jae had dinner with a woman in a restaurant.Minshew later learned that the necklace found at the crime scene came from a brand of women's necklaces called Harry Joyce.

At work, Zhenyuan confessed the truth of the entire incident to her boss.She insisted that the investigation should continue, even if it meant revealing her husband's secrets.After all, it would go a long way toward boosting ratings.Although the waiter in the cafe could not recall the woman who was traveling with Woo-jae, Tae-heon already had another suspicious candidate in his mind.

At work, Zhenyuan's colleagues mentioned another case in which a cult leader was arrested for neglecting to care for an injured follower, which ultimately led to the death of the other person.This makes Jung-won shudder, and she begins to wonder if Eun-chae was still alive when she left.When she washed her hands in the bathroom, she discovered that her hands were stained with blood.

Later, Zhenyuan confided her fears to the therapist.The therapist believes that this may be a psychological reaction caused by Jung-won's discovery of Kim Myung-sook's body.Zhenyuan also talked about her husband's affair, vowing to make him feel the pain she endured.

Tae-heon returns to the crime scene again to investigate, and this time he makes a major discovery.Jung-won runs into him in the parking lot of the building.Tae-heon invited her to the police station for further questioning and showed her the necklace he found at the scene - the same necklace Woo-jae gave to Jeong-won.He seriously asks if she was present at the crime scene.

In the past, Jeong-won told Tae-heon about her father’s cold case while Tae-heon was on surveillance duty.She said she fainted and did not see the killer's face, even though he was there.She then promised to catch the criminals and expose them on her show.They also decide to make this stakeout mission their first date, and she kisses him.

Back in the present, Tae-heon asks Jung-won about her necklace.He also learned about the erroneous text message from the therapist's clinic.Jeong-won insists she didn't go and says she would never kill someone the way her father was killed.Nonetheless, Tae-heon asked her to write down her actions that day.

Meanwhile, Woo-jae visits Jung-won's therapist Yoo Yoon-young.Their relationship is closer than one might think, and Woo-jae turns to her for help.

While pondering the loss of the necklace at the crime scene, Jeong-won almost crashes her car.Mingxiu, who was following her, offered to help, but she refused.He called Tae Heon and told him the same thing.

At home, Jung-won looks through the photos she took of Eun-chae’s body.There is no necklace in Eun Chae's hand.She asked Zeus to find the police crime scene photos.The next morning, Zeus sent her the photo.In these photos, Eun-chae has the necklace in her palm, but not the pendant.

At the police station, Tae Heon confirmed that Eun Chae bought the necklace himself and did not steal Zhen Yuan’s.Now, they need to focus on finding Woo-jae's mysterious woman, who was also seen entering the leader's palace that night.

Just as Tae-heon predicted, Woo-jae comes to them and demands to know why Jeong-won is being interrogated.Tae Heon confronts him about the third woman and says Eun Chae also knows about her.

At the news station, Jung-won’s boss says their show may be replaced.Jeong-won sees protesters outside her office when she arrives, but her boss warns her in time.He tells Jung-won that the CEO has decided to change the show and leaves.

While checking Eun-chae's call history, Tae-heon discovered that she called Mo Hyung-taek's secretary Song Hyo-sung.This was just three days before her death.The two detectives interviewed the secretary.He said that he accidentally discovered that Eun Chae was being threatened by a stalker and came forward.She took his number and later called him to invite him to dinner to express her gratitude.

Jeong-won tries to go to the CEO's house, but encounters Noh Ji-ho, who says her boss is asleep.Then Jeong-won gets a call from her colleague telling her about Chairman Seol’s relationship with the CEO of the company.She visited him and asked him to talk to the CEO.Chairman Seol agrees to do this if she stays with Woo-jae until the case is over.When Jung-won walks out, Woo-jae is waiting for her.He asked about her police interview, but she didn't explain anything and accused him of pretending to care.

Eun-chae's agent contacted the detective and said Eun-chae wanted to hire a bodyguard before she died.They told her Song's story about the stalker, and she recalled a similar incident.The agent recognized him from the list of security personnel at the leader's palace - a man named Kim Min-cheol.Tae Heon sees Woo Jae’s name marked on his calendar.Detectives found Kim Min-cheol and captured him.He said he went to high school with Woo-jae and borrowed money from him.

Jeong-won approaches her workplace, this time, talking to reporters.She shows support and love between Woo-jae and herself.In the office, Kang In-han tells them that the show has not been cancelled.But her colleagues seem betrayed by Jung-won's sudden change in behavior.

Later, Zhenyuan received a call from Hye-won, a woman who works in a treatment clinic.She explains why she had to tell the police about the text messages, and then says she was close to Eun-chae.After the call, Zhenyuan followed her on IG.

Tae-heon meets Jung-won in her hotel room and demands to know why she lied.He even thought it was part of a conspiracy between the two of them to kill Eun Chae.He then sees the photo of Eun-chae's body on Jung-won's laptop, but she turns it off before he can take a closer look.He then saw a red coat in the room and told Jeong-won about another woman Woo-jae had seen, who was wearing a red coat when she entered the leader's palace.

While taking more things from her house, Jeong-won meets Woo-jae.He said that he had joined his father's company, so his father would help Zhenyuan.He told her not to go back to the hotel.She told him to sleep in the bedroom and agreed to sleep on the couch.

While he slept, she looked for something.He caught her, but she said it was one of her USB sticks.She walked to the parking lot and placed a tracker on Woo-jae's car.She then listened to Woo-jae's recording from the USB drive she had hidden.

The next day, Jung-won tells Woo-jae that she’ll give him a chance.But she actually uses it to investigate him.Later, Jung-won admitted this to her therapist.She plays the recording of Woo-jae telling someone not to let anyone find out they were at the crime scene.She needed to find out who he was talking to.

She admits that she told Yoon-young for insurance, in case something happened.Yin Ying received the call and walked out.While she's away, Jeong-won spots a red coat on a hanger.She took a photo.At this moment, Tae-heon sent her a video of Woo-jae and the woman in red in a cafe.Finally, she realizes that this woman is Yin Ying.

Zhenyuan discovered that her therapist Yin Ying was actually the woman in red who had an affair with her husband.In Yinying's office, she saw a familiar coat and immediately confirmed it.Immediately afterwards, Yoon Young tampered with the text message that guided Zhenyuan to the wrong floor.Later, Zhenyuan received a call from her husband, inviting her to attend the opening ceremony of the foundation.She pretended to be calm and left the clinic, but recalled in the car that Woo-jae recommended her to come here.

Zhenyuan then contacted Ms. Choi, a nurse at the clinic, and accepted her invitation to have dinner.Meanwhile, Tae-heon and Myung-soo at the police station are reviewing the list of suspects, and the arrival of Kim Min-cheol makes them realize that he was on patrol when Eun-chae died.Tae Heon questioned him.

During dinner, Ms. Choi reveals that Eun-chae was also a patient of Yoon-young and that Yoon-young would film all consultation sessions, which shocked Jeong-won.On the other hand, Yoon-young watches a clip of Jeong-won’s consultation and meets Woo-jae in the apartment she is renting now.She warns him about the listening device Jung-won left behind and reveals that Jung-won knows he saw Eun-chae on the day she died.Yin Ying also said that Zhenyuan had blood on her sleeves during the consultation that day.Woo-jae is angry about this, and he doesn't want to ask her for help anymore, but he's upset about the listening device.

The next day, Jung-won finds Ms. Choi in the hotel room, trying to get Eun-chae’s therapy tape.Later, when she went to work at the company, she heard her colleagues talking about her husband. It turned out that Lu Jihao leaked the scandal.Afterwards, she goes to Woo-jae's house, searches the old room, and finds their high school photo.She immediately contacted Yin Ying.

At the police station, Tae-heon realizes that Eun-chae and her brother were born in Moon City, the city where Woo-jae and Min-cheol went to high school and where Mo Hyung-taek also worked.Except for Zhenyuan, all suspects are related to this place.Noh Ji-ho approached Tae-heon and asked about his relationship with Zhenyuan, but Tae-heon avoided answering.Later, Tae-hun visits the grave of his late partner Cha Jin-woo.

Recalling what happened three years ago, Tae-hyun angrily broke into his partner's car and found a box full of cash.Someone called to tell him the location of another detective, but by the time he arrived, the detective had fallen to his death.Jin Woo tells Tae Heon that Jung Won is also cheating on him.After his death, Zhenyuan quickly rushed to the scene.Tae-heon accuses her of dating him just to get the scoop on Jin-woo.

Now, Tae-hyun meets Jeong-won who comes to lay flowers.After their brief chat, Tae-heon goes to play baseball with a former police detective he's known for a long time.

When Jung-won returns home, she is confronted by Woo-jae, who wants to know if she killed Eun-chae.He said he just wanted to protect her.Jeong-won comments that now they are both suspecting each other of murder.

On the day of the opening ceremony of the charity foundation, Zhenyuan and her husband attended together, and the police detectives also appeared quietly.Yin Ying's unexpected appearance attracted everyone's attention. It turned out that she was invited by Zhen Yuan.Yoon-young and Woo-jae pretend to meet each other for the first time, which is suspicious.Zhenyuan received a text message from Ms. Cui, informing her that she had copied the video of Euncai's treatment process. This was the real reason why Zhenyuan invited Yinying out.

Woo Jae and Jung Won took to the stage to answer questions from reporters.Noh Ji-ho deliberately mentioned Eun-chae in an attempt to create confusion.Zhenyuan took the opportunity to say that she would report the results of the investigation on the show, hinting at what Ms. Cui revealed about Jin Shi's attack on Eun Chae.After Jin Shi heard the news, he couldn't hold back his impulse and left the scene in a hurry.

At this time, Zhenyuan noticed that Taeheon was following Woojae.She calls Tae Heon and asks to talk to him first.Seeing that Noh Ji-ho has been monitoring Zhenyuan, Tae-heon decisively pulled her into a storage room.He urgently asks Jung-won the real reason for defending Woo-jae.

Noh Ji-ho meets Woo-jae by chance and ridicules him about Jeong-won.Woo-jae angrily shakes him off, but overhears a staff member mentioning that there's a police detective in the storage room.When Jung-won and Tae-hun leave the room, Woo-jae happens to see them.He called Tae Heon and asked him to meet on the rooftop.

On the rooftop, Tae-heon questions Woo-jae about the identity of the woman in red.He also mentioned the coincidence of Munn City, which seemed to be inextricably linked to the case.Woo-jae is unwilling to answer, which makes Tae-heon even more convinced that Moon City is related to the case.The two sides almost got into a fight, but Zhenyuan arrived in time to resolve the conflict.

It turns out that Zhenyuan has been secretly listening.At home, Woo-jae gives her a USB drive with evidence of Eun-chae’s attack for her show.At the same time, Zhenyuan also received a video of Euncai's treatment sent by Ms. Cui.

On the other hand, police detectives discovered that Mingxiu's ex-husband was actually related to a chemical plant fire.After his death, Mingxiu deliberately approached Mou's family.Tae-heon points out that Myeong-soo is also inextricably linked to Moon City.

In Eun-chae's therapy video, she openly mentioned that Yoon-young and Woo-jae were in the same high school.She asked Yoon-young if she knew someone named Na-ri, saying she heard the name in Woo-jae's drunken ramblings.

Jeong-won takes a closer look at the high school photos she found of Woo-jae, then takes the train to Moon City.However, someone is following her through the town streets.Zhenyuan fought back decisively...

Tae-heon accidentally discovered that Jung-won was also on her way to Moon City, which piqued his curiosity and decided to follow her.However, this behavior is misunderstood by Jung-won as surveillance, and she sternly warns Tae-heon not to continue doing this.

Later, Zhengyuan learned about Jin Minzhe's existence from her colleagues.The next day, she visited Moon City High School, while Tae-heon visited the family of Kim Min-cheol's ex-husband, Kim Soo.At school, Zhengyuan carefully planned a fake surprise video to elicit more information.The vice-principal reveals Woo-jae's popularity at school, but little is known about his relationship with Yoo Yoon-young.At the same time, the vice principal also mentioned Woo-jae's hurried trip to the United States and Min-cheol's troublemaking behavior to Jung-won.

On the other hand, Minzhe released a statement online claiming to be the father of Eunchae's child.The vice-principal recalled that Minzhe threatened to harm himself because of the cold response of his crush Nali, and finally Woo-jae came forward to rescue Nali.Jung Won further confirmed that the third girl in the photo of Woo Jae and Yoon Young she saw before was Na Ri.However, a fire in the Bongtu factory in 2009 resulted in Na Ri's tragic death. This monument was funded and built by Woo Jae's father, Seol Pan Ho.

After returning home, Woo-jae learned about the necklace Jung-won left at the crime scene through a private detective and instructed him to further investigate Tae-heon.Meanwhile, detectives talk to Jin-soo's sister, who reveals that Min-cheol called her and insisted that Jin-soo was innocent.When the fire broke out at the Bongtu factory, Jin Xiu's sister asked Moo Hyung-taek for help, but he later regretted his promise.

Tae-heon then visits the vice-principal, while Jung-won goes to meet Jin-soo's sister.Both are trying to track each other down.Tae Heon begins to connect Yoo Yoon Young to the entire incident.Eventually, the two investigators meet, and Tae-heon asks Jung-won about Yoon-young.His distrust of her becomes increasingly apparent, even accusing her of going to Eun-chae's crime scene.Jung-won refuses to answer and leaves.

Looking back three years ago, Zhengyuan was accidentally pulled away by Taeheon when attending Cha Zhenyu's funeral.He wants her to be honest and tell him that her real motive for approaching him isn't just to spy on Jin-woo.However, his questioning revealed deep suspicion of Zhengyuan.

Finally, the two had dinner together.Despite the tension between them, Tae-heon pulls Jung-won to shelter from the rain when it suddenly starts raining on the way home.There, he admitted that it was painful for him to watch her go through so many difficulties.

After Tae-hyun got drunk, Jung-won had to help him back to the room.In his drunken state, Tae-heon asks Jung-won to help him trust her.At this time, Woo Jae called and overheard Tae Heon's voice.He simply asked Zhengyuan when she would be home the next day and hung up.

Yin Ying unexpectedly appeared when Woo Jae was drinking alone. She showed a photo of Zheng Yuan's sleeve stained with blood, implying that Eun Chae's death was related to Jung Won, which aroused Woo Jae's strong desire to protect his wife.Yin Ying then gave a bottle of propofol as a gift, but Woo Jae smashed it against the wall angrily.

Early the next morning, Zhengyuan insisted on driving Tae-heon off in person.In the restaurant, she tells Tae-heon about the entanglement between Yoon-young and Na-ri in detail.When they realize that the fire at the Fengtu factory may be the key to solving all the mysteries, the two decide to visit the police detective in charge of the case in search of new clues and evidence.

A damaged watch turned up in the case sparked new speculation.The watch, which had lost its battery, was similar to watches from two previous murders, and detectives revealed it had belonged to Li Nali.Tae-heon therefore brings up the metaphor of a clock, suggesting that there may be a common murderer behind these events.

On the way back, Taixian and Zhengyuan noticed signs of being followed, but ultimately failed to intercept the suspect vehicle.Shockingly, the driver was Mou Hengze's assistant, which made the case even more complicated.

At home, the relationship between Woo-jae and Jung-won is strained due to misunderstandings.Woo-jae is suspicious of Jung-won's whereabouts, and Jung-won is disappointed with Woo-jae's distrust.Meanwhile, Min-cheol's phone call provides new clues to Tae-heon, who reveals that she regularly sends money to victims of factory fires, hinting that she may be connected to the case.Woo-jae learned of Tae-heon's whereabouts through a private detective and began to doubt his identity.

The meeting between Xue Panhao and Mou Hengze revealed the transformation of the power relationship between the two.The former master-servant relationship has now been reversed, and Xue Panhao seems to intend to use Mou Hengze to achieve his own goals.This change heightened the tension of the plot and paved the way for subsequent developments.

Early in the morning, Woo-jae discovers Jung-won's secret in the office, further escalating the crisis of trust between the two.However, after a frank confrontation, the misunderstanding was resolved.At work, Lu Zhihao's invitation brought new opportunities to Zhengyuan's team, and the reconciliation between Aina and Zhengyuan also paved the way for teamwork.

Tae Heon's bribery investigation unexpectedly involves more inside stories.He discovered that it was the same police officer who was investigating him, and that the culprit behind the scenes was his boss.This discovery shocked Taexian, and he began to re-examine the people and things around him.

Zhengyuan met Mou Hengze by chance on the street, and their conversation revealed that a larger conspiracy was brewing secretly.Meanwhile, Tae-heon decides to meet Yoon-young, hoping to get more information about the case from her.

Tae-heon has questions about Yoon-young's whereabouts during Eun-chae's murder.Yoon Young candidly admitted that she briefly left the clinic that day, but refused to reveal the identity of the person who was traveling with her.At the same time, Pan Hao was furious because of the plummeting stock price of the company and yelled at his son and daughter-in-law.When Zhengyuan refused to join the company, he threatened to reveal their agreement and pretend to reconcile.After Zhengyuan left, Woozai threatened his father with his own relapse as a bargaining chip, which seemed to have successfully prevented him from pursuing Zhengyuan.

Zeus told Zhengyuan that the information about Yin Ying is limited. At present, it is only known that the clinic nominally belongs to Mou Xiulin, and Yin Ying is Mou Hengze's daughter.Zhengyuan was surprised to find that they had studied together in Munn City.On the other hand, Hyung-tae-k asks Jung-won’s boss In-han to reveal an important story.When police searched Kim Min-cheol's residence, they found a hidden knife, which was suspected to be the murder weapon.Although Minzhe admitted to following Eunchae after his arrest, he firmly denied murder and insisted that the knife was not his.

Woo-jae accidentally learns about Jung-won and Tae-heon's past relationship.Zhengyuan went to Woozai's office to verify Minzhe's case, but left in a hurry, telling him not to wait because she needed to work all night.After testing, the blood stains on the knife were confirmed to be left by Eun-cai.Tae-hyun received a call from Jung-won. As reporters surrounded her, the two agreed to meet at her residence. Unexpectedly, Woo-jae seemed to be following her there secretly.

After the two meet, Tae-heon reveals that Yoon-young’s alibi is reliable.During the conversation, he mentioned the past breakup between the two.Zhengyuan is dissatisfied and angry at Tae-heon's accusation, but Tae-heon apologizes to her for the misunderstanding.At this time, Woo-jae broke into the apartment and was angry that Zhengyuan was working at her ex-boyfriend's house, and had a conflict with Tae-heon.Zhengyuan takes Yuzai home, and the quarrel between the couple escalates. Yuzai suspects that Zhengyuan is being taken advantage of by Taeheon.Frustrated by Jung-won's cold reaction, Woo-jae actually took out several vials and entered the ice bath.

Pan Hao met with Mou Hengze, revealed his plan to build a new resort, and sought his support.Tae-heon investigates the man who reported Min-cheol as the murderer and discovers that Jin-se is behind it.At the press conference, Inhan announced that Minzhe was the murderer. Although Zhengyuan knew that this was Mou Hengze's instruction, she did not resist.Finally, Jung-won and Tae-heon met at Kim Myung-sook's house. Tae-heon discovered something unusual about the knife, but did not explain it in detail.When parting, Tae-heon revealed that it was Gong Joon-ho who revealed their past to Woo-jae.After a forensic review, Tae-heon firmly believed that the knife was used by Eun-chae to injure himself, not a murder tool, so Min-cheol was able to clear the charge of murder.

As Zhengyuan searched for clues, she came to an empty boxing ring - a place often used by police detectives to vent their emotions.She immediately realized what was happening and met Jin Shi there by chance.In order to learn more about the situation, Zhengyuan pretended to believe that Minzhe was the murderer.At this moment, a moneylender came to the door, and Jin Shi was busy dealing with it. Zhengyuan took the opportunity to search the kitchen and found a set of red knives, one of which was missing.Soon after, she discovered the bag that the lender had returned to Jin Shi, and discovered some abnormalities in it.

Recalling what happened three months ago, Zhengyuan noticed that her colleague Barron's bag was very similar to the moneylender's bag, even the keychain was exactly the same.This raised questions in her mind.

At this time, Zhengyuan and Taeheon met again to discuss Jin Shi's motives for framing Minzhe.During the conversation, Zhengyuan clearly told Taexian that there should be no more emotional entanglements between them.After saying that, she left to talk to Aina and tell her the past events with Tae Heon.

Meanwhile, Yoon-young is repairing a broken bowl, and Soo-rim is there.Yoon-young shows deep concern for Soo-rim and hands her a bottle of propofol.Yoon-young's actions reveal her deep feelings for Soo-rim.

Soon after, Jung-won unexpectedly bumps into Soo-rim at a mental health clinic and asks her for a later interview.However, when she meets Yoon-young, Woo-jae's sudden appearance breaks the original plan.The couple's meeting originally arranged by the doctor caught both of them off guard.Yoon-young is aggressive when questioning Jung-won, and Woo-jae reveals his deep connection with Yoon-young.

Yoon Young claimed that her relationship with Woo Jae was extraordinary and they even studied abroad together.Zhengyuan is keenly aware that Yoon Young has deep affection for Woo Jae, but she thinks this relationship is one-sided.The doctor believes that this is just a past incident when they were young, and Yin Ying chose to disclose all this to eliminate misunderstandings.Jung-won ends the meeting by revealing that she knew about the secret recording.She firmly told Woo Jae that she didn't want to see him again, and then left decisively.

While talking to Zeus, Zhengyuan realized that Zeus had been secretly observing her, which made her feel uneasy.Suddenly, a man attacks her from behind and knocks her unconscious with chloroform.This incident made Zhengyuan deeply shocked and angry, and she realized that she was facing great danger.

Zhengyuan was accidentally kidnapped by Cha Euncai's secretary Jin Shi. This incident aroused great dissatisfaction from Mou Hengze, because he discovered that Jin Shi had not only appeared at Minzhe's house, but also carried a knife.On the other hand, Tae Heon questioned Mo Hyeong Taek's secretary Song Hyo Sung's behavior of following him to Mo Eun City.Mou Hengze firmly denied any connection with Jin Shi and severely reprimanded Song Xiaoxing.

Jung-won wakes up in Eun-chae's brand new office and finds herself tied to a chair.Jin Shi forced her to confess to the murder and took out the bag she had seen at Jin Shi's house as evidence.Meanwhile, Woo-jae is worried because Jung-won hasn't returned home, and he asks Tae-heon if he's seen her, but Tae-heon says he hasn't.

Recalling the day Kim Myung-sook was killed, Kim Se was conducting surveillance outside her home under Song Hyo-sung's instructions.He found that there were other people in the home, so he went in to check and found that Jin Mingshu was dying and there were traces of stab wounds on her body.There was a bag filled with cash nearby, and Jinshi grabbed the bag and fled the scene.

Early the next morning, Taixian was determined to find Zhengyuan's mobile phone and found her car through the location information.He follows Jin Shi's car and eventually discovers Zheng Yuan's location.At this time, Jin Shi was already drunk, but Zheng Yuan managed to cut the tape with a corkscrew and free her hands.She breaks free and locks herself in the bathroom.Tae-hyun arrived in time and stopped Jin-se's attack on Jung-won.Afterwards, they left the building and Woo-jae arrived at the scene.Zhengyuan was sent to the hospital for treatment.

At the hospital, Jung-won tells Tae-heon that she thinks Zeus has been spying on her.When news of Jin Se's arrest came, Tae Heon asked him if he did all this under Mo Hyung Taek's order.Jin Shi admitted his crime.They decided to ask Zhengyuan to write an article exposing Mou Hengze's crimes.Before leaving, Tae-heon hugs Jung-won, apologizes for getting him into this dispute, and confesses his feelings for her.

The next day, Yoon-young goes to the hospital to visit Jung-won, but it's not out of concern - she shows Jung-won a photo of her bloody sleeve.Woo-jae walks in and says he’s thrown away the shirt.When Yoon-young threatens to show Tae-heon the photo, Woo-jae forces her to leave by threatening to reveal that she illegally prescribed him propofol.

Woo Jae revealed to Jung Won that he became addicted to drugs while abroad.He was on the verge of committing suicide when he met Zhengyuan and tried to quit drug addiction.Jung-won wonders why he still can't sleep after taking sleeping pills, and Woo-jae reveals that it's because a girl he once loved passed away, but he doesn't elaborate on the details.

While helping Zhengyuan sort out her clothes, Woo-jae's thoughts drifted back to the past.A flashback shows Jung-won and Woo-jae’s past.They talk about work, and Woo-jae gently removes a necklace from her hair that he gave her as a gift.He placed the necklace gently on the table beside him.

At this time, Zhengyuan received a call.The revelations about Mo Hyung-ze in her article led the congressman to decide to hold a press conference.At the meeting, he admitted that he was a sponsor of Cha Eun-chai and other young people from broken families.He claimed that he supported Encai until she graduated, creating an image of himself as a generous donor.

At the same time, Tae-heon holds a portrait of the person who sent cash to Kim Myung-sook.There was a glimmer of recognition in his eyes.On the other hand, Woo-jae has doubts buried in his heart. He wonders whether Yoon-young took away Jung-won's necklace that day.He clearly remembered placing the necklace gently on the table.In order to find out the truth, he called her, used an apology as an excuse to hide his impulsiveness, and invited her to dinner.

Zhengyuan's team warmly welcomes her back.She was keenly aware of Barron's absence.Tae-heon brings a portrait that is very similar to Barron, revealing that this person is the mysterious figure who sent cash to Ming-sook.After returning to work, Zhengyuan couldn't wait to track down Barron's home address and decided to go check it out in person.She walked quietly into the house and found that the door was unlocked.What is displayed in front of him is a complex set of computer equipment, revealing Barron's unusual secret.In the next room, the wall is covered with photos and newspaper clippings, most of which are closely related to the Mou Hengze and Fengtu fire cases.Through the unread text messages on the desktop, Zhengyuan was shocked. She realized that Barron was the mysterious “Zeus”.Barron's sudden appearance caught Zhengyuan off guard, and before he had a chance to explain, he chose to flee the scene, leaving behind a string of mysteries to be solved.

Woo Jae carefully prepared a romantic dinner for Yoon Young.In this warm atmosphere, the two candidly shared their confusion and powerlessness in love.After the meal, Woo Jae sent the drunk Yoon Young home safely and began a detailed search of her apartment.His eyes finally fell on an inconspicuous USB flash drive, which contained photos of Zhengyuan, especially her accessories and clothing.One of the photos of the necklace caught Woo-jae's attention. It was exactly the same as the one seen at the crime scene.At this moment, Woo-jae is convinced that Yoon-young is the culprit who framed Jung-won for murder.When Yin Ying woke up from her deep sleep the next day and found that the USB flash drive was missing, she fell into a burst of hysterical laughter.Soon after, she handed over a key piece of evidence during an interrogation at the police station - a photo of Jung-won sitting next to Eun-chae's body.This photo closely linked Zhengyuan to the crime scene, pushing her to the forefront.

Yoon Young hands Tae Heon the photo of Jung Won sitting next to Eun Chae’s body.While at work, Jung-won received a call from Woo-jae.He asks to meet her and shows her a photo of Jung-won's necklace in Yoon-young's hand.Then, a news report surfaced about an inappropriate relationship between Jung Won and Tae Heon.Woo-jae expressed concern about this and asked Jung-won about the authenticity of the report.

Myung Soo also called Tae Heon to warn him to avoid contact with Jung Won during this period.Realizing she may be facing a career crisis, Jung-won reveals to her boss that she has a prime suspect in mind.She asked her bosses to give her some time to publicly reveal the true culprit before her show was taken off the air.

Aina asked Zhengyuan about the report, and Zhengyuan insisted that it was untrue, but she could not reveal the truth to her husband.Aina is sensitive to the fact that Zhengyuan has feelings for Taexian.They then talked about Barron and his true identity.Aina recalled that Barron once said that he and Zhengyuan suffered from the same disease.

Meanwhile, Tae-heon tries to analyze Jung-won’s photos privately.However, he was blocked by Woo-jae, who angrily clashed with him.During the fight, Tae Heon revealed his deep love for Jung Won.She rejected him.Tae-hun tells Woo-jae that Jung-won should file a restraining order against him to get rid of these unfounded rumors.On the way home, Woo-jae arranges an interview with a reporter.

Jung-won and Tae-hun meet secretly at the campsite.She apologizes to Tae-heon for the news report and reveals her suspicions about Yoon-young.However, Tae-heon thinks Yoon-young’s alibi is impeccable.As Tae-heon ponders the photo, Jung-won admits she lied to him and promises to explain everything soon.

On their way back, Jung-won comes across an article written by Woo-jae about a restraining order against Tae-heon.The police detective revealed that this was his advice to Woo-jae and told Jung-won to pay attention to her own safety.After the detective left, Zhengyuan stepped forward and hugged him from behind.She admits that she tried to suppress these feelings but ultimately failed.He moved closer to her and asked her to give him a minute.Then they kissed passionately.

Elsewhere, Yoon-young suddenly breaks into Woo-jae's room and kisses him.She questions why he killed Eun Chae and framed Jung Won, calling him a monster.Yoon-young retorts that he knows everything Woo-jae did.However, she promises to protect him.

The next day, Jung-won had an in-depth conversation with Woo-jae.Woo-jae seems to accept Tae-heon’s explanation for Jung-won’s rejection of him.However, Jung-won admitted that she gave in to temptation.She admits that she likes Tae Heon and realizes that the situation is irreversible.She leaves the room, leaving a distraught Woo-jae behind.

After a while, Tae-heon visits Woo-jae and shows him Jung-won’s photo.He said the photos proved the existence of hidden cameras and suggested Zhengyuan was framed.He says Woo-jae is the only person he can turn to now.

Zhengyuan's thoughts drifted to Mou Xiulin, after whom Yinying's clinic was named.She goes to Mou Xiulin's cafe and talks about her relationship with Yoon Young.Zhengyuan lied that Yinying's alibi turned out to be false, and she was hiding in room 1401 where Euncai was killed.Mou Xiulin inadvertently reveals that she knows the layout of the room, but when Zhengyuan presses further, she lets Zhengyuan leave.Outside the store, Barron stared at Zhengyuan silently.

Back at the police station, Tae-hyun received a call from Jung-won.She told him that she suspected Mou Xiulin was related to the case.Later, Tae-heon talked with the police detective in charge of the Bongto factory fire case.The detective confirmed that Mou asked them not to report the second ignition during the fire.Meanwhile, the politician himself spoke to Kang In-Han, who revealed that Jung-won's show is about to be cancelled.

Zhengyuan suddenly received a text message from Zeus, which contained a series of photos on Mou Xiulin's mobile phone, including photos of Room 1401.Zhengyuan immediately informed Inhan of the incident, but was alertly aware that Mou Hengze had been secretly bribing him.Before leaving, In Han revealed that he had secretly operated to ensure that Jung Won would get three minutes of live time on TV.Jung-won carefully prepared her show and revealed her plan to Tae-heon.

While delving into Bongto's case files, Tae-heon discovered key evidence.However, when Zhengyuan's show started airing and she was about to reveal the truth, the studio suddenly cut off her live broadcast.Meanwhile, Tae-heon acted decisively and arrested Yoon-young for illegally prescribing propofol.This information was provided by Woo Jae.

Elsewhere, Mou Xiulin received an urgent notice requiring her to board a plane to New York immediately.At the same time, Tae-hyun interrogated Yoon-young and asked her if she had ever been to Room 1401.Yoon Young admitted that she had indeed been there and revealed that Woo Jae was there too.In the flashback, Eun-cae revealed the news of her pregnancy to Woo-jae, while Yoon-young chose to leave at the critical moment.

Yoon-young continues to lie to Tae-heon, but Woo-jae reveals the truth to the detective through the headset.Woo-jae explains that Yoon-young blackmailed him, threatening to reveal his affair unless he sent her away.Tae-heon then mentions Lee Na-ri, revealing Woo-jae's romance with her when they were in school.A flashback shows a young Woo-jae and Na-ri dating while Yoon-young angrily observes.

Tae-heon further hints that Yoon-young might be the mastermind behind all the murders committed by Moo Soo-rin.He noted that the two had been close friends since high school and accused them of being involved in the arson attack at the Bongto factory.At this time, Yoon Young mentioned Jung Won's photos, which had been hidden by Tae Heon, but Yoon Young officially mentioned them in the record.She also mentions the blood stains on Jung-won's sleeve, hinting at her guilt.Yoon-young confidently laughed and said that she had expected Woo-jae to do this, so the detectives found nothing when they searched her office.Later, Myung Soo confirmed this and told Tae Heon that the search indeed found nothing.

At the same time, Mou Xiulin, who was praying in the church, fell into memories.She thinks back to the day Eun-chae was murdered, when Yoon-young sat next to her and told her that Eun-chae suspected her and her father.Yoon-young warns that Eun-chae will expose their crimes in the Kim Myung-sook murder case and the Bongto fire.In order to solve the problem, Yin Ying gave Mou Xiulin a knife.

Seol Pan-ho asks to meet with Woo-jae, who reveals that Yoon-young will not be arrested unless there is conclusive evidence.He provided Xue Panhao's contact information with Mou Hengze.

The next day, Jung-won meets Aina and tells her that she plans to hold a press conference that day.However, Zhengyuan was one step late.Before she was ready to reveal the truth, a video of her in room 1401 was leaked to the police.As a result, Tae-heon was relieved of his duties.Jung-won is surprised to find the police searching her house when she returns home.They find blood on her shoes and Jung-won is arrested.

Tae Heon was fired for not reporting Jung Won's photo.A video of Jung-won sitting next to Eun-chae's body led to a police search of Jung-won's home, leading to her arrest.At the same time, Yin Ying was released.

As Zhengyuan was being escorted to the police station, reporters such as Lu Zhihao surrounded her.At the same time, Woo-jae urgently asked his father to help Zhengyuan, but his father believed that the pressure of public opinion was too great, and only by uncovering the real culprit could the storm be quelled.

Yin Ying meets Woo Jae by chance, who promises to prove that she and Mo Xiulin committed a crime together.Faced with Yoon Young's determination, Woo Jae even knelt down and asked for help.They planned to put the blame on Mou Xiulin in order to rescue Zhengyuan.In exchange, Yoon-young asks Woo-jae if he will marry her.

On the other side, Mou Hengze reconsidered his cooperative relationship with Xue Panhao because his daughter-in-law became a murder suspect.Yin Ying happened to meet Mou Xiulin who was about to leave the country and gave her a clock.Mo Xiulin was grateful and agreed to help Yin Ying hide a knife in the memorial hall where Zhengyuan's father's ashes were stored in order to frame the crime.

As expected, Myung Soo meets Tae Heon by chance and reveals that Mo Soo Lin is about to leave the country.Tae-hyun received an investigation call from the internal police department and received a text message from Seol Woo-jae.When he excuses himself to go to the toilet, Tae Heon escapes from the building.Woo Jae fell into deep thought when facing the divorce agreement and marriage registration form.After returning home, she found Yin Ying lying in the bathtub. Yin Ying showed the form as evidence and secretly installed an eavesdropping application on Woo Jae's phone.Although Yoon-young tries to kiss Woo-jae, he pushes her away and apologizes.

Mou Xiulin went to the columbarium as planned and hid the knife behind Zhengyuan's father's ashes.Zhengyuan in the cell became increasingly anxious, and the police found the hidden knife in time.Taixian rushed to the scene and showed the video of Mou Xiulin placing the knife, thereby reinstating his duties and successfully arresting Mou Xiulin who was about to leave the country.

Later, Tae-heon took Jung-won out of prison and informed Woo-jae.Mou Hengze and Xue Panhao drank tea at the congressman's home and laughed at each other about Mou Xiulin's fate.Jung-won starts a conversation with Tae-heon, who promises to bring Yoon-young to justice and reveals that Woo-jae leaked information about Moo Soo-rin.Facing numerous media, Zhengyuan apologized at the door of the police station, and Lu Zhihao asked her why she fled the scene to keep her position on the 9 o'clock news program.

Woo Jae waited for Jung Won on her way home and took her home.Jung-won fell asleep on the way, and when Woo-jae tried to wake her up, she unconsciously called out Tae-heon's name.

In the interrogation room, Taixian questioned Mou Xiulin and mentioned an entry in her diary in 2009.The camera flashes back to the scene when Mou Xiulin and Yin Ying were young, standing next to Li Nali's body. They lit the Fengtu Chemical Factory on fire, causing a fire.

Tae Heon reveals that Kim Myung Sook's blood stains appeared on the diary, implying that Mo Soo Lin killed the housekeeper because of the diary.Flashing back to the past, Mou Xiulin was fighting fiercely with Kim Mingshu, and Kim Mingshu was stabbed.Immediately afterwards, Jin Shi appeared and stole the bag containing money.

Tae-heon turns the focus to Eun-chae's murder, showing Moo Soo-rim murdering the actress in cold blood through flashbacks.Tae-hyun tries to force Mo Soo-rin to admit that she committed these crimes under Yoon-young's orders.However, Mou Xiulin's shaking and falling to the ground caused the police chief to suspend the interrogation.

The meeting between Yin Ying and Mou Hengze revealed the financial transactions between the two.Yin Ying proudly stated that Mou Xiulin's love for her was not her fault, further highlighting her selfishness and indifference.

As Mou Xiulin refused to cooperate, the police team was in trouble.However, Zhengyuan did not give up. She found Jiang Renhan and tried to unravel the connection between Mou Hengze and the murder.Zhengyuan's intuition told her that Mou Hengze's silence meant that Yinying had his secret.Renhan revealed that Xingze's wife fell down the stairs 13 years ago and became a vegetative state, which hinted that there were more secrets behind the case.

When reporters besieged Mou Xingze, Zhengyuan bravely confronted him face to face.Mou Xingze played a recording of Yin Ying and Mou Xiulin talking about the crime, and revealed the fact that Yin Ying witnessed Mou Xiulin pushing her mother down the stairs.He also showed scars on his body and claimed that he had also tried to kill Mou Xiulin.Finally, he asked everyone to help catch Yin Ying.

An angry Yoon Young then called Mo Hyung Taek and accused him of portraying herself as a victim.After hanging up the phone, Yoon Young started walking towards the lake, thinking about Woo Jae.Meanwhile, Tae-hyun shows Moo Soo-rin a video of her father, and Moo Soo-rin insists that she never tried to kill her father.She is shocked and dismayed to learn that it was Yoon-young who got her into trouble.

Jung-won was attacked by Yoon-young on her way home, who injected her with an unknown substance.

Three years ago, Yin Ying stumbled into Woo Jae's studio drunkenly to express dissatisfaction with his unfinished novel.She realized that the next day, Woo-jae and Zhengyuan would enter the marriage hall, which made her feel extremely troubled and uneasy.

Now, Yin Ying stands by the calm lake and she decides to end her life.She gently removed the watch battery and quietly set the hour hand to ten o'clock.At the same time, Tae-heon received a message that Yoon-young's mobile phone location showed that she was near a bus station.The police immediately launched a search, and Tae-hyun found a woman holding Yoon-young's mobile phone and jacket, but this seemed to be just a cover-up.

Woo Jae got home and received a call from Tae Heon.At almost the same moment, Yin Ying sent a message revealing that she had taken Zheng Yuan hostage.Faced with Tae Heon's questioning, Woo Jae had to lie and immediately called Yoon Young.She provided an address and asked him to come alone.

Fortunately, Tae Heon saw through Woo Jae's lie.He learned from the administrator that Woo-jae drove away from home in a hurry.At this moment, Zhengyuan woke up on the roof and found that she was tightly tied with a rope, and Yinying held the other end of the rope.Yinying plans to end her life with Zhengyuan at 10pm, that is, 15 minutes later.She confides in her obsession with stopping time and hopes that by committing suicide and killing Jung-won, Woo-jae will always remember her.

Woo-jae finally arrives at the scene, and he pleads with Yoon-young to let go of his hatred.However, Yin Ying told Zheng Yuan in a low voice that the real murderer of Eun Chae was actually Woo Jae.Just when she was about to jump off the roof, Tae Heon arrived in time.Yinying jumped down, but the two men quickly grabbed Zhengyuan and the rope.Yoon Young said she had no regrets, broke away from Tae Heon's hand and fell heavily to the ground.

In the police station, Mou Xiulin felt mixed emotions when she heard the news of Yin Ying's death.She blamed her father.At the same time, Moo Hyung-taek sat outside Park Jin-soo's shop, repenting for being framed in the Bongtu fire.

Zhengyuan returned home, Yinying's words always lingered in her ears.Before she died, Yin Ying revealed that the truth was hidden in Zheng Yuan's most cherished items.Zhengyuan started looking through her things and finally found a divorce application.When Woo-jae comes home, Jung-won tells him firmly that she wants to end the marriage.

Woo Jae tearfully accepted Zheng Yuan's decision, she moved out of the house and temporarily went to Aina.When the two women got together, Zhengyuan opened up and shared her pain and confusion.She lost her husband, her show, and her job, and her life seemed to be in trouble.

Tae Heon vented his frustration in front of the boxing bag.However, his mood instantly improved when Zhengyuan called and asked for help.They meet outside and Jung-won wants him to send her her treatment records.He then asked with concern about her future plans.Jung-won revealed that she was going through divorce proceedings and planned to submit a letter of resignation.Tae-heon comforts her, and then she gathers her courage and asks if he will wait for her.He agreed without hesitation.

The next day, Zhengyuan went to the company as usual and began to organize her belongings.She distributed some items to her colleagues and made a suggestion to Lu Zhihao, hoping that he could investigate the assassination of Mou Hengze.Woo-jae's father called and invited Jung-won to join his company.She told him frankly about the divorce and agreed to sign a confidentiality agreement.

When she left the company, she suddenly felt dizzy and fell to the ground in pain.Woo Jae happened to be passing by and immediately stepped forward to help her up.He drove her home and she fell asleep on the way.Woo-jae tries to wake her up, but she seems to have lost consciousness.He rushes her to the hospital, where the doctor tells him that Zhengyuan collapsed due to dehydration and stress, and that she is pregnant.

Tai Xian visited Mou Xiulin in the cold prison.Despite the difficult situation, Mou Xiulin still firmly trusts Yin Ying. She made it clear to Tai Xian that she had never stabbed her father.Then, she revealed a past incident related to the Bongtu fire.Through a flashback, young Li Nali witnessed Mou Xiulin feeding rat poison to rabbits.Afterwards, Mou Xiulin and Yin Ying teamed up to trick Na Li into the factory, knocked her out and set her on fire.However, after escaping the scene, Mou Xiulin saw Nali staggering out of the sea of ​​fire.Mou Xiulin chose to hide this shocking discovery from Yin Ying.

In the hospital bed, Zhengyuan slowly woke up.Woo Jae sat on the edge of the bed and gently told her the exciting news - she was pregnant.His face beamed with joy and he earnestly asked her to get back together with him for the sake of their children.However, Zhengyuan's heart did not seem to be shaken by this tenderness, and she firmly expressed her determination to divorce.

At the same time, in the police station, Tae-hyun learned a depressing news from Myung-soo - Na-ri's body was too damaged for DNA testing.At this time, Mingxiu revealed a surprising fact, Li Barun was Li Nali's biological brother.Barron came to Aina's house and met Zhengyuan and Aina.He shared with them his and Mou Xiulin's speculation that Nali might still be alive and discussed the possibility of another crime.When Zhengyuan saw him off, she was accused by a police detective of being cold-hearted.The detective suddenly realizes that today is the death anniversary of Zhengyuan's father, and he speculates that her indifference is because of this special day.

In the subsequent episode, Jung-won undergoes an ultrasound examination.She asks with mixed feelings about the possibility of abortion, but the image doesn't give a clear answer.After returning home, Zhengyuan looked at her treatment records.During a therapy session, she talked to her doctor about Woo-jae's book.Yoon Young's last words are strikingly similar to the last line of the book.This aroused Zhengyuan's strong curiosity. She hurriedly opened the pages of the book and found a memory card sandwiched inside.

The memory card contains the video of the day Eun Chae was murdered.In the video, a man walked into the room when Eun-cai was dying and stabbed her again brutally.Zhengyuan is shocked to find that the knife used by the murderer is exactly the same as the weapon that killed her father.At this moment, Woo-jae walks into the room, and Jung-won's mind flashes to his face when her father was murdered.This scene made her shudder.

Jung-won and Woo-jae watched a video together at home, in which a man stabbed Eun-chae.Later, Woo-jae entered the room, wearing a black hat and jacket.Zhengyuan entrusted him to buy a cake to commemorate the anniversary of her father's death, and checked his car by the way.She discovered that his car had been to Munn City and that his shoes had mud on them.That night, they held a solemn memorial ceremony for their father.After the ceremony, Woo Jae tried to communicate with Jung Won, but she chose to rest due to exhaustion.

Early the next morning, Zhengyuan woke up from a nightmare.When she arrived at Aina's apartment, Tae Heon was waiting there.He revealed that he would go to Munn City to look for Nali, suspecting that the found body Li Nali might be a missing female immigrant.Tae Heon held Jung Won's hand tightly and tried to comfort her.

Later, Taixian met a friend of the missing woman Zhang Hualan, who disappeared in the fire at the Bongtu factory.Zhang Hualan worked part-time at Fengtu Factory on the day of the fire.Local police detectives proposed tracing the records of 911 calls made that day.In addition, Tae-heon also learned that Mujin Resort was built on the former site of Bongtu Factory and had achieved remarkable success.

Li Balun returned home and found the note left by Zhengyuan.The note mentioned Na Li's matter and asked him to get in touch with Zhengyuan.In Munn City, Taixian came to the bus stop where he and Zhengyuan once stayed together.He sent the photo to Zhengyuan, and her reaction seemed ambivalent.Later, Zhengyuan went to Woo-jae's office building and learned that the cafe in the building had a passage leading to the back alley, which made Woo-jae's alibi no longer reliable.

Zhengyuan received a call from Barron and agreed to meet with him.During the meeting, she revealed to Barron about the missing immigrant women and accused him of making sure she was the first to discover Kim Myung-sook's body.Baron then revealed that he had met Zhengyuan's father Sangjun.

In a flashback, Sangjun is interviewing Barron and his family.Later, Barron heard Shang Jun's fierce confrontation with the murderer on the phone.A few days later, Shang Jun was murdered.

Barron promised to communicate with Zhengyuan after finding more information, and then left.Meanwhile, Pan-ho is happy with the news that Woo-jae is about to become a father.Woo Jae was appointed as the head of the second Mujin Resort.He then burned the photo with Na Ri and Yoon Young and the vinyl record she gave him.

Woo-jae sent a message to Jung-won, but she chose to turn off her phone.She then went to a gynecology clinic.Secretary Kong enters Woo-jae’s office to deliver some important information to him.He rushed to the clinic and accused Zhengyuan of having an abortion, but she insisted that she did not have an abortion.

After returning home, Jung-won revealed to Woo-jae that her mother left her when she was very young.After her father died, she tried to find her mother for comfort, but received no response.Now, she has decided to keep the baby because she doesn't want to feel alone in her life.Woo Jae suggested that she postpone the divorce until after the child is born.

Tae Heon tried to call Jung Won, but she didn't answer.Later, Woo Jae comes to see him.He revealed to Tae Heon that Jung Won was pregnant and asked him not to embarrass her.

Tae Heon is shocked when he hears the news.He called Zhengyuan and the two finally met.Before Zhengyuan could say anything, Taehyun was the first to express his love for her.Jung-won revealed that her emotions have changed a lot since she realized she was pregnant.Although Tae-heon still wants to be with her, she begs him to forget his previous confession.

After returning home, Aina comforted Zhengyuan.Tae Heon drank to drown his sorrows, and Secretary Kong stayed by his side.He advises Tae-heon not to get too attached to someone who has no future.

At the same time, Mo Hyung-taek is devoting himself entirely to the campaign for the post of Gangwon Province.Secretary Song revealed to him that the police were actively looking for Li Nali's whereabouts.At the police station, Tae-heon listened to the recording of the 911 call from the day of the Bong-tu fire. The person on the phone claimed that his friend had passed out.

After visiting the police detective in Fengtu, Mou Hengze seemed extremely excited.Later, Pan Hao called and the two made an appointment to meet.Pan Hao was in a happy mood because of the news about his grandson. However, his good mood disappeared instantly when Mou Hengze suggested that Li Nali might have escaped from the factory.The congressman also learned that Tae Heon had the 911 recording.He hinted that the caller had some relationship with Pan Hao.

A recollection of the day of the fire shows that Xue Panhao and Mou Hengze were together.At that time, Mou Hengze's status was obviously more prominent.Pan Hao seemed stressed about something.Later, Mou Hengze noticed that the headlight of Pan Hao's car was broken.

Back to reality, Zhengyuan watched the video Yoon Young left for her.She recalls Woo-jae expressing his reluctance to go on vacation to New York because he felt lonely while studying there.Jung-won's father passed away in January of that year, and Woo-jae left for the United States in February.

Zhengyuan visited Mou Xiulin and asked her if she knew Woo Jae's whereabouts in January of that year.Mou Xiulin said she could not remember clearly, but there may be records in her diary.Jung Won asked Myung Soo to check the diary and told him not to tell Tae Heon.After checking it, Myung-soo told Jung-won that according to the diary, Yoon-young visited Woo-jae in a hospital in Seoul on January 10.

Woo Jae received a visit from Pan Ho, who revealed that Tae Heon had the 911 recording in 2009.The news so disturbed Woo-jae that he hallucinated and saw a dead body while driving home.A memory flashes back, and young Woo-jae hits Li Nali with his car.

The story slowly unfolds from the memories of 2009.Young Woo Jae drove his father's car to the factory to pick up Na Li.Unfortunately, he bumps into Nali who is running on the road.He quickly dialed the emergency number and rushed Nali to the hospital.At the same time, Woo-jae's father called to ask about the situation, and Woo-jae told the truth.Knowing that Nally was seriously injured, her father ordered him to return home and avoid going to the hospital.

Time flies, Woo-jae steps into his father's house again, carrying a heavy secret - Eun-cae's matter.In the memory, Eun Chae once called and threatened Woo Jae, claiming to expose the murder he mentioned in his dream.Back in reality, the father and son sat around to discuss how to deal with this difficult problem.Woo Jae was determined to hide the truth, and for the sake of his children, he chose silence.

When Tae-heon has lunch with his secretary Gong, Gong suggests that he give up Jung-won for the sake of their future.Zhengyuan came to her father's grave alone. She firmly stated that for the sake of her children, she must find out whether Yuzai was really the murderer.

She embarks on a journey to Moon City, home to the Bongtu Fire Memorial.At the same time, Aina called and told Zhengyuan that Woo-jae's father had announced the news of her pregnancy.Zhengyuan felt mixed feelings in her heart. She called Woozai, but she was decisive, saying that no article could change her decision.She also learned that Woozai was participating in the Xinmujin Resort project in Muen City.

After meeting his father, Woo-jae sternly warned him not to harass Jung-won.Then, he left to see Mou Hengze.Zhengyuan observed all this secretly.Over lunch, Mou Hengze tried to get more benefits from the resort project.He used the information he had about Woo-jae's 911 call to blackmail, while Pan-ho cleverly shied away from responsibility and threatened to reveal the secret behind Moo Hyung-taek's solar plexus scar.Not to be outdone, Mou Hengze showed off a bloody piece of Yuzai's car headlight, putting Pan Hao in trouble.

Tae Heon also heard the 911 recording and confirmed that it was Woo Jae who made the call.They realize that finding Nally's body is the key to uncovering the truth.In Moon City, Jung-won followed Woo-jae to a hotel room.However, Woo-jae then leaves the room.

Meanwhile, Lee Barron was digging in a wooded area.He was holding a white windmill in his hand, which was a souvenir he got at the Fengtu Memorial Hall.He finds Woo-jae in the woods and follows him to a mysterious place.I saw Woo Jae kneeling on the ground, pouring banana milk into the soil - this was Na Li's favorite drink during her lifetime.

Just then, Barron discovered a skeleton in the same place.However, he is not alone.Someone suddenly attacked him and strangled his neck until he passed out.As the man prepared to bury Barron, two security guards suddenly appeared, forcing the attacker to flee.Later, Tae Heon received an emergency call.

He hurried to Munn City and recognized Barron's body.Zhengyuan saw him and the other policemen and walked over.Tae Heon reluctantly told her about Lee Balun.She looked at his body and recalled their past, and couldn't help but burst into tears.

Later, Tae-heon realizes that Woo-jae is also in Moon City.He further investigated and found that the skeleton turned out to be Li Nali's.He immediately told Zhengyuan about this shocking discovery.As a determined reporter, Jung-won is determined to find Woo-jae and uncover the truth.She checks the hotel security footage and a security guard tells her that Woo-jae went to the hotel bar and never left the hotel.This clue made her even more convinced that Woo-jae was inextricably linked to Na-ri's death.

Back in Woo-jae’s hotel room, Jung-won shows the video clip of the man killing Eun-chae.She said in a firm voice that this man also killed her father.Woo Jae looked shocked and firmly denied the accusation.In order to prove his innocence, he immediately called the director of the hospital and confirmed in front of Zhengyuan that he had been receiving treatment in the mental hospital during the period when her father was murdered.After learning the truth, Zhengyuan breathed a sigh of relief, and the pressure in her heart finally eased.

However, at this moment, Pan Hao spied something from the window of the hotel room, and a trace of alertness flashed in his eyes.

Early the next morning, Woo-jae accompanied Jung-won to the scene of Na-ri's death.With Taixian's tacit approval, they stepped into the silent forest.Detectives requested security videos from nearby stores, but coincidentally, all footage had been deleted.They arrived at the crime scene, and Tae-heon looked Woo-jae straight in the eyes and asked him if he had seen Na-ri on Christmas Eve 2009.Woo-jae was silent for a moment, then nodded and told her that Na-ri had gone to the factory.

On the way through the forest, Zhengyuan suddenly felt uncomfortable.She walked into the bathroom, and Tae Heon took the opportunity to play the 911 recording for Woo Jae.In the recording, Woo-jae's voice is clearly audible, explaining that the driver hit Kim Min-cheol.He assures Tae-heon that Min-cheol can vouch for him.Tae-heon chuckles softly and reveals that he had obtained the crucial security footage from the store the night before.

In the video, a man dressed in black walks into the forest that night at the Bongtu Memorial Hall.Woo Jae shook his head and denied that it was him.Tae Heon's eyes became sharp and he promised to catch the real culprit.Before they parted, Jung-won showed Tae-heon the video that Yoon-young left for her and the contact records with her father.

Fragments of memories take us back to 2008.A student attempted to steal an item from a man's pocket - a knife with a spiral pattern.And this man is Secretary Gong.

The story paused at this moment, and a car slowly stopped in front of them.The car door opened and Gong stepped out, his eyes wandering between Woo Jae and Jung Won.A trace of determination flashed in Zhengyuan's eyes, and she knew that the truth was before her eyes, and Yuzai also clenched his fists, preparing to face the coming storm. A battle between truth and lies was about to take place.

After watching the video of Eun-cai's assassination, Woo-jae felt deeply anxious and immediately called Pan Hao to ask him why he killed Eun-cai in this way.In the flashback clip, Eun-chae met Pan-ho on the last day of her life. She revealed the news of her pregnancy to him and showed that she knew about Na-ri, but she still chose to stay with Woo-jae.

Pan Ho frankly admitted that he ordered Kong Jun Ho to end Eun Chae's life, and further revealed that Baron was also a victim of his men.Woo Jae continued to ask whether Kong Junhao was also the murderer of Zhengyuan's father.Pan Hao just responded coldly and asked Woo Jae to come see him in person.Later, Pan Hao spoke to Kong Junhao and confirmed that it was him who ordered the removal of Zhengyuan's father.Pan Hao didn't want Woo Jae to uncover the truth, so he ordered Kong Jun Hao to find a solution.

After returning from their trip to Munn City, Woo-jae and Jung-won were told that they had to meet with President Jang to discuss the Munn City resort project.However, due to Zhengyuan's unwellness, they decided to put the matter on hold for now.

When Kong Junho chatted with Tae Heon, the latter seemed extremely nervous.It turns out that Tae-hyun is the student in the previous flashback clip, and he recognized the knife in Kong Jun-ho's hand from the video Jung-won gave him.Despite his misgivings, Tae-heon invites Gong Jun-ho to dinner.

At the same time, Jung-won firmly told Woo-jae that she must find the murderer.Tae Heon recalled the past with Kong Junhao, and he firmly believed that Kong Junhao was a trustworthy person.By tracking the mobile phone, Mingxiu discovered that Kong Junhao's whereabouts were closely connected to Pan Hao's office.

Mou Hengze began to suspect that Pan Hao might have more secrets.When he learns that Tae-heon is tracking Gong Joon-ho's phone, he thinks it might be the key to uncovering the truth.

On the way to send Zhengyuan home, Woozai received a call from his father.At the same time, Tae-hyun saw the news that Jung-won's father passed away on January 10, 2010.Coincidentally, he happened to have dinner with Kong Junhao that day.The young Tae Heon had just been admitted to the police academy, and the older police detective specially arranged this dinner to encourage him.However, now Kong Junho suddenly canceled his dinner plan with Tae Heon.

Woo Jae hurried to his father's house and begged him to confirm whether he was related to Seo Sang Kyun's death.Pan Hao admitted that Shang Jun mistakenly thought it was Pan Hao sitting in his car, so he followed him.Shang Jun took a video of Pan Hao's hit-and-run accident and used it to blackmail him, so Pan Hao ordered him to be removed.Woo Jae was in great pain and felt that he should not have married Zheng Yuan in the first place.Pan Hao warned him not to tell Zheng Yuan the truth.

Myung-soo drinks with Tae-heon and discusses the possibility that Gong Joon-ho might be the murderer.Tae Heon felt as if he had been betrayed by someone he admired.The next day, at the news station, when Jung-won was sorting through Barron's belongings, she and Woo-jae were eager to find the murderer.

Tae-heon receives Lee Na-ri's autopsy report and connects it to Woo-jae's story about the car accident.He and Myung-soo conclude that Pan-ho ordered Kong Joon-ho to dispose of Na-ri's body.Tae-hyun knew that Kong Jun-ho was in urgent need of money because his sister suffered from a rare disease.

Tae-heon went to the hospital to visit Gong Jun-ho's sister, although he pretended it was just a coincidence.She revealed that she was diagnosed with the disease in 2009, which left Gong Junho with a heavy debt.When she was about to commit suicide, Kong Junhao told her that she had found a sponsor - the chairman of a construction company.

Tae Heon told Myung Soo about this new situation.At this time, Zhengyuan came to the police station hoping to learn more information, but Taehyun did not tell her everything she knew.Suddenly, Tae-heon suggested that Jung-won leave Woo-jae and his family and promised to take her away from this place.

After Zhengyuan received the photos in Barron's notebook from Mingxiu, she carefully discovered the clues about her father.When she meets her boss In-han by chance, she learns that her father Sang-gyun is investigating a construction project in Moon City, and the fire at the Bongtu factory actually helped the Moon City company to rise rapidly.This makes Zhengyuan can't help but suspect that Pan Hao or Moo Hyung-taek may have something to do with her father's death, because they were both deeply involved in the project.

After returning home, Zhengyuan carefully looked through her father's belongings, and a notebook marked “Muen City Gangster” caught her attention.She speculates that this refers to Pan Hao and Mou Hengze.At this time, Pan Hao called and asked Zhengyuan to meet him.

Recalling that three years ago, Woo-jae helped Jung-won handle a case against a director of a company in Moon City.Woo Jae mentioned that his father used to save important documents in paper form instead of electronic files.

Faced with Pan Hao's threat, Zhengyuan decided to move back to Woo Jae's house as a strategy to obtain evidence of Pan Hao's crime.This was beyond everyone's expectations, but Zhengyuan firmly stated that she would move back the next day.

When leaving, Jung-won tells Woo-jae that she would rather live in her current house because the other house holds the memory of her kidnapping.Woo Jae gently told her that the house had been sold.Meanwhile, Myung-soo and Tae-heon track Gong Joon-ho, and Tae-heon is convinced that his knife must be found.

In Han introduced Jung Won to a reporter who was also investigating corruption in Moon City.The reporter revealed that a truck accident once blocked the road, preventing fire engines from reaching the burning factory in time.The only clue was a black cell phone used by the truck driver.The reporter agreed to help Zhengyuan contact the truck driver who is currently serving a sentence.

Taixian witnessed Zhengyuan moving into Pan Hao's house and was warmly welcomed by Kong Junhao.Subsequently, the reporter called to inform him that the truck driver's mother had committed suicide.Tae-hyun observes Kong Jun-ho's movements outside the house and follows him quietly.

A staff member told Zhengyuan that there was a locked room next to Pan Hao's study and entry was strictly prohibited.Zhengyuan went upstairs to check the locked door on the pretext of sending flowers to the chairman's study.She then checked the study and found some locked drawers.However, Pan Hao's timely appearance let her know that he already knew her purpose.

Pan Hao warned Zheng Yuan not to act rashly.At the same time, the reporter from earlier called and told Zhengyuan that she found the information about the truck driver's mother.The woman wanted to meet Zhengyuan, and Zhengyuan agreed.

Tae-hyun received a call from Myung-soo while spying on Gong Jun-ho.Learning that someone turned himself in to kill Lee Barron, Tae-heon decided to confront Gong Joon-ho directly, accusing him of all the murders.He begged Kong Junhao to surrender, but was refused.The two get into a fierce struggle when Tae-heon tries to search for his knife.Tae Heon found the knife, but the fight continued and Tae Heon was stabbed.
