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.
