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...
