[5] Yoo Min-ho, CEO of an IT company, is the prime suspect for the murder of Kim See-hee, his former mistress, after the police find him with her body in a hotel room that was locked from the inside.

Shin-ae travels to Min-ho's remote snow-covered cabin to meet him for the first time and decide if she wants to take the case.

Shin-ae advises Min-ho to be truthful with her, as she suspects that the case is connected with the disappearance of a young man named Han Seon-jae.

Fearful of having their affair exposed, See-hee convinced Min-ho to get rid of the other car and its dead driver, Seon-jae.

However, Young-seok reported Seon-jae's disappearance and shared a description of See-hee and the car with the police, making her a suspect.

Min-ho approves of this defense strategy and claims that he saw Young-seok in the room, but Shin-ae calls this out as a lie.

Shin-ae reveals that she lied about Seon-jae's mother working in the hotel, in order to force Min-ho to tell the truth.

Shin-ae suggests that Min-ho was the real decision-maker of the incident instead of See-hee: he was driving the car and he decided to cover it up by disposing of the body.

Shin-ae signs the agreement committing herself to be Min-ho's attorney and proposes that they plant evidence on Seon-jae's body to let See-hee be posthumously solely responsible for covering up his death.

She and Young-seok kidnapped the real Yang Shin-ae in order to stage the meeting with Min-ho and have him confess where Seon-jae's body is.
