Chae won seems to develop super human powers because he breaks the handcuffs on him and sends one of the police men flying. Shocked by this, they have him arrested. Secretary Jeong lets Yun ja Yu know of Hoseong’s death and Chae won’s arrest. She doesn’t react much as she simply tells Secretary Jeong to let Hoseong’s family know of his demise and send them her condolences. Then she heads to the station. Meanwhile, Secretary Jeong secretly calls Seonu Geun, Prime minister Lee’s father letting him know of what happened, that Mr Kim killed someone and it’s only a matter of time before Yun ja Yu figures out she’s a spy who told Mr Kim their whereabouts so she plans to flee. But the prime minister tells her to remain since there is no evidence leading her to the crime.
He then calls his son and tells him to catch Mr Kim immediately before the police do but Prime minister Lee is at first reluctant but eventually calls the Chief inspector of police who tells him about Chae won’s super human abilities. Prime minister Lee is very fascinated when he watches the video.
Yun ja Yu visits Chae won in prison and asks him why he assaulted the officers but he responds he didn’t plan to do that as he just felt hot. However, he is most concerned about who revealed their location to Mr Kim and is determined to find out. He lets Yun ja Yu know beforehand that he’ll be leaving the company and she’s not surprised. Before they part ways, he tells her a secret of Secretary Jeong being suspicious.
Yun ja Yu meets with the Chief inspector of police and they show her the dash cam taken from Hoseong’s car which shows him and Chae won chasing after Mr Kim. Unknown to them, Yun ja Yu is wearing a tech glass that enables her to link the video to Mr On who then identifies Mr Kim’s face thanks to Yeongsil. After they are done with the meeting, Mr On informs Yun ja Yu that Mr Kim set his car on fire at a public place. The chief inspector is surprised that she already is aware of that. She secretly has her men send the chief inspector of police a picture of Mr Kim’s face.
Mr Seo learns from Mr On that the jacket he had given Hoseong didn’t save him and that he died through a hole in the suit. This leaves him completely devastated. Chae won gets released from prison and the officer in charge tells him it’s due to his connections. He calls Yun ja Yu to ask if she was responsible for getting him out but she denies it. He hangs up when a group of men suddenly pick him up. They take him to meet Prime minister Lee who is fascinated that he has super powers but Chae won replies that he only did what he did because of the tech suit. He turns the table on him telling him that it’s suspicious how the family of his friend, the terrorist were able to travel abroad and live a good life over there.
He expresses his suspicions of his father Seonu Geun being responsible for the attack on his grandfather because he went against Bf, a company he was interested in. It was the reason why he divorced his mother. Prime minister Lee gets riled up and starts attacking Chae won but a hit to his nose has him bleeding. That’s when Chae won discovers prime minister Lee is sick with Haemophilia.
He sends him out and a little later, Yun ja Yu arrives. Chae won leaves the two alone and Prime minister Lee confirms his suspicions on why she acts differently with Chae won when she has no interest in anyone let alone men. It’s because he’s her biggest breakthrough, a secret she wants no one else to know. Yun ja Yu comes clean, admitting that she is indeed culturing human organs but she wants to create a free world where everyone can afford to have it. Prime minister Lee thinks differently, believing that immortality should only belong to the rich and powerful, people like him. He wants Yun ja Yu to make him like Chae won or he threatens to dissect him and order a seize and search warrant against her company. He tells Yun ja Yu he likes her and that she should hang on to him while she still can but Yun ja Yu takes his words as he’s challenging her and leaves. Unknown to them, Chae won hears everything due to his super hearing.
As Yun ja Yu leaves, she signals to Chae won to join her in the car. While driving, they discuss and she mentions that Secretary Jeong is indeed the spy. Hoseong had told her their whereabouts and that was how Mr Kim got to them. To confirm, they set up a trap for her. Mr On calls Secretary Jeong to let her know that they have found Mr Kim and just as they predicted, she secretly makes a call to someone. Just then, Mr On and Miss Hong cramp her there and she’s brought to the investigation room where the others are gathered.
She denies being a spy, trying to get into Yun ja Yu’s feelings claiming she had left her job as a lawyer to work for her. But no one believes her. Yun ja Yu asks if she was secretly dating Prime minister Lee or his father, if that was the reason she became their spy. But Chae won thinks differently and believes it’s because she was enticed by becoming immortal. He presses his hand deep into her shoulder causing secretary Jeong much pain as he reveals she purposely recruited him so that he would be giving them information. Their main purpose was to take over BF and they got to him through the former president. When Yun ja Yu hears this, she realizes that Chae Won is also a spy
Secretary Jeong was the one who introduced Professor Kim to the support group so he could meet Mr Kim and was the one who made a man jump on top of Yun ja Yu’s car which caused her accident.
Yun ja Yu speaks with Chae won privately and he admits he’s a spy but only for the former president not Prime minister Lee. He only came to her to find out if she was behind the terrorist attack which killed several of his men but it turns out she wasn’t responsible after getting to know the kind of person she was. Yun ja Yu is hurt by this. She thinks he may have spilled other information to them but Chae won tries to let her know that didn’t happen. He asks for one more chance to make things right since he would be leaving soon. He tells her his only mission is to find the terrorist and the man responsible for Hoseong’s death. Yun ja Yu tells him to do whatever he wants and that he is fired.
As soon as he leaves, she tells Yeongsil to pack her things out of Chae won’s house as she breaks down. (Omo…divorced couple)
Meanwhile, Mr Seo and Mr On use a device attached to Secretary Jeong’s head to fish out memories of the bad things she has done but she fights against the device. The only thing she thinks of is a pale looking woman who seems familiar to Mr On. However, when Yun ja Yu returns to whisper into her ears that she has already framed her for working with Mr Kim and fleeing afterwards. Now that she’s declared missing, anything can happen to her.
Meanwhile, Prime minister Lee rallies the support of his ministers to go against BF. Yun ja Yu goes back to Chae won’s house and starts parking her things. However, she’s hit with memories of her, Chae won and Hoseong on the rare times they sat together and talked. Hoseong dreamed of owning a house and getting married to his girlfriend. Chae won had teased him for having such a dream at only twenty six when he himself wasn’t yet married. Chaewon had revealed he was selling his house to pay off his niece’s school fees abroad because her father abandoned her due to her allergy to milk. Yun ja Yu had spoken of her desire to go to school abroad but only her sister was given the opportunity due to finances. Hoseong had joked that now, she could sponsor a hundred children abroad. Yun ja Yu feels bad after remembering that as she wonders how his girlfriend must feel about his death.
Chae Won and Mr. On meet at Hoseong’s burial. Mr On expresses his disappointment in Chae won for suspecting Yun ja yu. After their talk, they separate and as Chae won leaves, he notices Hoseong’s junior brother looking completely devastated outside the building.
With Yun ja Yu gone, Chae won returns home. Meanwhile, Secretary Jeong tries to manipulate Mr On into letting her go by lying that she had feelings for him but he didn’t notice because he only had eyes for Yun ja Yu. However, Mr On doesn’t fall for it though.
Yun ja Yu decides to expose her cultured organs to the public causing Prime minister Lee to be shocked. He sets up a press conference to go against her, claiming she’s only promoting her work for money but Yun ja Yu offers free surgery to terminally ill patients and announces she would perform the surgery on herself by replacing her organs with cultured ones. She’s doing all of this to ensure the procedure is safe for everyone. Her staffs at BF are surprised by this emergency announcement, especially Mr On who rushes to find her.
But on the way, he suddenly recalls the face of the woman Secretary Jeong was thinking of. He had seen her wailing at the funeral of the man who jumped on top of Yun ja Yu’s car. He calls Yun ja Yu to tell her this but she’s been held up by Chae won who tries to convince her not to do the surgery but to use him as her proof of success. Yun ja Yu stubbornly refuses and Chae won asks why she’s going so far but Yun ja Yu responds that it’s because she wants to subdue her enemies. Chae won decides to take matters into his own hands Yun ja Yu asks what he’s up to but he responds that he also has something he cannot give up on and leaves.
He meets with the former president to plant the idea in his mind that his ex son in law was responsible for the terrorist attack given that the only other person he had told of his surprise visit to the army camp was his daughter. The former president refuses to believe him and sends him away in anger So Chae won meets the next person who can help him, his daughter.
