Yingyuan accidentally bumped into Dr. Wu lying in a pool of blood at her family's vacation home. When she was panicking, Sijiang revealed to her that she had discovered Dr. Wu who was unconscious before Yingyuan arrived.After careful consideration, the two decided to temporarily avoid calling the police to avoid attracting public attention. Instead, they chose to secretly transfer Dr. Wu to a trustworthy hospital for treatment.

At the hospital, Sijiang was full of doubts about what happened to Dr. Wu. She intuitively felt that the matter might be related to Zai Zhen, because Zai Zhen seemed to be inextricably linked to the matter.At the same time, Young-won received a mysterious text message, which contained “complete lies” and included intimate photos of Jae-jin and another woman.Young-won further discovered that the medical association that Jae-jin had mentioned to her did not actually exist, which made her more suspicious of Jae-jin.

However, Si Jiang firmly believed that Jae Jin was innocent, and despite the evidence before her eyes, she still insisted on defending Jae Jin.The two had a disagreement, but put their dispute aside for the time being.After Sijiang left, Yingyuan went to the hospital alone to visit her mother who had dementia, and the relationship between the two became particularly tense.

On the other hand, Si Jiang returns to the vacation home with Park Kang-sung, the owner of Soft Hand Company.In the office and bedroom on the second floor, they accidentally discovered clues to Jae Jin's extramarital affair.These discoveries reminded Sijiang of her husband's past betrayal. She felt mixed feelings and decisively ordered Kang Cheng to clean up the scene to cover up all the secrets.

Ying-won ran into her younger brother Ying-min on the way to Jae-jin's office, and Ying-min revealed to her the circumstances of his encounter with Jae-jin on the road.What's more, they learned that Kang Cheng's nephew was Yingmin's friend, and this relationship paved the way for the subsequent plot development.Yingyuan used her wisdom to find key clues from the clinic's surveillance video. She found scenes of Jae-jin and Dr. Wu rushing somewhere.What shocked her even more was that she found Dr. Wu’s mobile phone in the back seat of the car.

At the hospital, Young-won manages to unlock the phone with Dr. Oh’s thumb.She was surprised to find that there were a lot of photos of Jae Jin saved on her phone, and there were even photos of Jae Jin and Sa Jiang when they were young.These discoveries made Young-won more suspicious of Jae-jin, and she decided to show the evidence to Sa-jang.

However, Sa Jiang insists that she and Jae Jin are just ordinary friends. She believes that Dr. Wu's one-sided obsession with Jae Jin is the root cause of all this.In order to cover up Dr. Wu's disappearance, Sijiang pretended to be Dr. Wu and sent a message to the clinic staff, falsely claiming that Dr. Wu would be on leave for a period of time.

Meanwhile, Young-won and Jae-jin had to concoct a lie to their son Do-hyun, explaining that Jae-jin was on an indefinite work trip.However, at this moment, Young-won received a call and learned that a bug was found in Jae-jin's clinic.It turns out that when Jae Jin and Dr. Wu were away, it was Si Jiang who installed cameras in the clinic and tried to monitor all activities in the clinic.

Si Jiang shows Young Won a video evidence that shows Jae Jin holding a bloody metal rod.However, Si Jiang still firmly believes that Jae Jin could not have tried to murder Dr. Oh, and she believes that this is all a deliberate attempt to frame their family.

At this time, they unexpectedly met Dr. Wu's partner Gao Jingtai, who revealed shocking news - Dr. Wu was missing and he was actually a policeman.The news shocked and frustrated Yingyuan and Sajiang, who originally planned to handle the matter quietly to avoid police involvement.But now, the situation is beyond their control.

In order to find Dr. Wu as soon as possible and get rid of her mobile phone, Yingyuan and Sa Jiang decided to go to Dr. Wu's apartment.Sajan claimed to be South Korea's Agatha Christie, and she cleverly cracked the password on her cell phone.However, just when they were about to succeed, Jingtai suddenly came to the apartment.

In desperation, Yingyuan and Sajiang hid their mobile phones in the closet.When Kyung-tae dialed Dr. Oh's cell phone, it rang in the closet.The two were panicked and at a loss.Fortunately, Kang Cheng appeared in time. He claimed to be Dr. Wu's uncle and lured Jingtai away, buying them time to escape.

At the same time, Do Hyun spent an unforgettable time with Moon Tae Oh.The friendship between them further deepened, paving the way for the subsequent plot development.

After returning home, Yingyuan and Sijiang met a private detective Zheng Douman.It turned out that he had been investigating Li Shina's situation at the request of Khmer.Dou Man provided them with conclusive evidence of Jae Jin's extramarital affair with Se Na, and told them that Lee Se Na was an extremely suspicious woman.The men she was associated with eventually met misfortune, and she became the beneficiary of their insurance money.This discovery made Yingyuan and Sijiang deeply suspicious of Li Shina's motives.

In addition, the plot also reveals a secret that Si Jiang has been hiding - she actually already knew about Jae Jin's extramarital affair.Facing Yingyuan's questions and accusations, Sijiang was speechless.As a result, Yingyuan had a fierce dispute with Sijiang, and she vowed to find Jaejin herself and uncover the truth of all these mysteries.
