The episode opens up with Tae Oh and Hye Won still in conversation. Hye Won asks if Tae Oh will help her but he replies that will never happen. Hye Won believes it’s because he doesn’t want her getting in the way of his ambitions but tells him that although he has no intentions now, he will support her one day. Tae Oh leaves her feeling melancholic. He arrives home and to his surprise, sees In ha ha waiting in front of his house eating ramen.
Tae Oh asks why he returned but In ha simply replied that he didn’t feel like sleeping alone. He tells Tae Oh that he would sleep over and without waiting for an answer, heads inside the apartment.
The next scene shows the Kang family all having breakfast. Suddenly, Kang Huiji suggests they invite In ha for dinner saying that she has missed him and that they can’t ignore him because he’s still family. Her mother chastises her and her elder brother berates her but to their shock Chairman Kang agrees that they should invite In ha.
Mrs Kang and the chairman talk privately. She is upset that he wants to invite In ha into their home reminding him that he had promised to keep him away from their family. But Chairman Kang tells her that she can’t control him. He also lets her know he is aware of the inheritance waiver she gave to In ha without his approval and right in her presence he calls In ha to invite him to dinner.
In ha is shocked to hear from his father and happily accepts. As the call ends,Tae Oh comes out from his apartment and In ha informs him about it. Tae Oh is surprised that the chairman called earlier than he had expected although he had suspected he would call eventually.
Angered, Mrs Kang gives Chairman Kang the contract In ha had signed and tells him to do whatever he likes with it. Tae ho and In ha talk privately with each other in a quiet classroom. Tae ho predicts that Chairman Kang is not sincere being the cold blooded man he is and is only trying to punish Mrs Kang for bringing up the waiver first before he did. They conclude that his kindness to In ha would only last for a short while and that soon, he would show his true colors. In ha has to be careful.
Meanwhile in his office, Chairman Kang chastises his assistant Assistant Chu for letting the inheritance waiver take place without his permission. He tells him he’s thinking of letting another law firm take his place and wants to acquire a company called Milton because he feels it would push Kangah forward. But then he threatens Attorney Chu that if the information about the waiver or any of his plans gets out, he would conclude that Attorney Chu is responsible for it. To Attorney Chu’s surprise, Chairman Kang gives him control of Milton and tells him to hold onto the waiver because they might need it one day. Delighted, Attorney Chu promises to keep things quiet.
The Kang’s second son Kang Seonju meets with the professor who presents him with Tae Oh’s report, passing it off as his own. Kang Seonju is immediately impressed with the strategy of the co prosperity cooperation center and tells the professor to resign as he would become the center director. The professor praises him as the new chairman but Seonju warns him that before working for Kangah, he should learn to be discreet. Professor promises to be careful.
In ha drops Tae at his construction work. As he watches him leave, he is frustrated that he still works there. Suddenly, he gets a call from Huiju. She tells him that she wants to see him instead of going to her tutoring class. She then invites him to have dinner with her at Daejoon, an expensive restaurant and informs him that he should thank her because she had begged their father to let him come to dinner. In ha is disappointed when he hears this.
Huiju is sketching Tae Oh’s face when In ha arrives, a bit tipsy. She is disappointed he didn’t bring her a thank you gift but In ha says she can ask him for anything. Huiju isn’t sure he can get her what she wants. He says her mother will be angry with her for ignoring her lessons but Huiju says her driver won’t spill plus she has already bribed her tutor. As they talk, a waitress enters to take their order. In ha is surprised to see that the waitress is Hye Won. Huiju asks if they know each other. In ha responds that she is a friend. Huiju then asks if Hye Won also knows Tae Oh and Hye Won replies that she does.
Huiju then says with veiled sarcasm that she doesn’t like her man being around other women. Noticing In ha and Hye Won’s discomfort, she says it’s a joke but then Hye Won counters that she as well doesn’t like her man with other women. The air is charged with tension as Huiju and In ha make their orders.
After dinner, the two leave and as Huiju enters the car, she asks when they would see each other again and if he would bring Tae Oh along but In ha ignores her words and waves her off as the car drives away.
In ha then goes back to see Hye Won in the restaurant and they talk privately. He apologizes to her on behalf of his sister. Hye Won accepts adding that she was quite rude to Huiju as well. In ha then asks if she would reconsider his offer for a relationship but Hye Won replies that she’s not ready to date as she doesn’t trust people. She leaves In ha dejected.
Tae ho finishes work at the construction place and heads home while In ha returns home thinking about Hye Won’s words. He thinks to himself that he would make her trust him by all means necessary.
Tae ho enters the bus and coincidentally meets Hye won. He sits in front of her and she starts talking philosophically about time and money but Tae Oh tells her to stop talking nonsense and get more sleep. Hye then says she wishes she can buy time.
The next day, In ha goes to the family house at Busanjae for dinner. The eldest son Kang inju sees him and is hostile. Huiju enters and tells In ha not to mind him. Inju takes offense and calls her a brat. In retaliation, Huiju bites his finger causing the wine bottle he was holding to crash to the ground. Inju’s wife and servants come to intervene. As they take inju away to get treated, Mrs Kang appears blaming the recent commotion on In ha. She tells him to do what’s right and leave.
Mr Moon informs Chairman Kang that In ha left immediately after the commotion and asks if he should call him back but Chairman Kang tells him there’s no need.
While treating Kang Inju’s finger, his wife warns him to stop letting Huiju get to him. Then Inju says it was worth it because he has helped his mother get rid of In ha. She hates him so much that she didn’t even decide the dinner menu and that what happened gave her the right excuse to kick him out. Inju feels he has scored a good point on her side.
Tae Oh meets In ha at the beach where he is reminiscing. In ha tells him that he already knows what must have happened. Tae Oh doesn’t comfort him. Instead, he tells him to kill the emotional Baek In ha and become Kang In ha who doesn’t have time to worry about emotions. He tells In ha to tolerate all the insults and humiliations to come and that he would make him the perfect third son of the Kang family. Now that Kang Seonju has the cooperation strategy with him, it’s only a matter of time before their plan begins.
At the Kang’s mansion, the family is having dinner and Huiju is disgusted with her family for acting like nothing happened. She calls them psychopaths and leaves the dining room. Her mother goes after her and while they are away, Chairman Kang berates Inju for insulting him by causing In ha to leave. Inju implies that it was his mother that sent In ha away. But Chairman Kang doesn’t listen and is determined to punish him.
Meanwhile Mrs Kang follows Huiju to her bedroom and slaps her. She tells her there will be consequences to her actions before leaving the room to meet Mr Moon. She questions him about Huiju’s recent obsession with In ha. Mr Moon responds that it could be because of her new tutor who is a friend of In ha. Mrs Kang is shocked to hear this. Just then, a maid rushes in and informs them that Huiju is missing. Mrs Kang and the maid go to her room but she’s not there. Mrs Kang then instructs the maid not to inform the chairman.
Meanwhile, Huiju had left her home in a rage. She ignores her mother’s calls but then panics when she realizes how lonely and dark the street is. Huiju suddenly calls Tae oh and tells him she ran away.
Next, we see them sitting on a bench beside the road. Huiju thanks Tae Oh for not telling In ha but Tae oh insists that she goes back home. Huiju refuses and just then, Hye Won walks by and sees them together. Huiju and Hye won trade words disguised as insults to each other. Suddenly, In ha drives towards them and Huiju is surprised that Tae Oh told In ha her whereabouts. She refuses to leave unless he comes with her. Hye Won asks for a ride since she and Tae oh are neighbors. Huiju is shocked to hear this. In ha drives them, dropping Tae Oh and In ha at their place. As they leave, Huiju asks her brother if he likes Hye Won. Although In ha denies it, Huiju can tell he’s lying. She hopes that Hye Won can like him so that she can have her chance with Tae Oh. Before entering the car, Huiju looks back at his house thinking to herself that the bad feeling she felt upon meeting Hye Won the first time was justified.
Tae oh is watching Hye won staring longingly at a couple strolling the streets when he suddenly receives a message from Mr Moon that his contract was terminated.
In ha drops Huiju in front of her house. She asks him if her mother would approve of Tae Oh living with them. She isn’t comfortable that he’s close with Hye Won. In ha laughs and tells her she knows nothing about Tae Oh but Huiju giggles that twenty days is enough for her to know someone. She skips off excitedly.
Meanwhile, Tae Oh and Hye Won are outside a convenience store talking. Hye Won asks him where they would be in ten years. Tae Oh replies that they would be where they are meant to be. Hye Won asks him if In ha would still be with him. Tae Oh then tells her not to use him to get to In ha. She should go to him directly. He tells her he hopes she wins this war.
The next morning, Huiji is mad when she hears that her mother hired a new math tutor. She had wanted to relax that day but decided to go to school despite her maid’s insistence.
In the car, her driver notices that her mood is down and tells her to relax. However, Huiju suddenly brightens. She tells him to stop the car and boards a taxi. Her driver Mr Lee is worried and wants to know where she’s going but Huiji doesn’t tell him. But she goes to see Tae Oh at his class in university. Tae Oh feels burdened by her presence. After the lecture, she follows him everywhere crying that he didn’t give her a proper farewell after getting fired but Tae Oh isn’t moved by her tears. Then age confesses that she likes him. But Tae Oh rejects her and even in her presence calls Mr Moon to return the money he paid. Huiju’s pride is wounded and she accepts the rejection coolly calling Tae Oh an employee who lived under her father’s money. She calls her driver to pick her up but in the car, she’s a bawling mess, crying her heart out at being coldly rejected.
Meanwhile, Hye Won had seen Tae Oh and Huiji together. She meets Tae Oh in the library and tells him he was too harsh on Huiji. She suggests that he can also reach his goal by getting close to her. However, Tae Oh gets angry at her for entertaining such an idea. Meanwhile, In ha overheard their conversation and wonders what Hye Won is really up to.
Hye Won’s mother steals a huge amount of money from a group of thugs. They find Hye Won at school and demand that she repays the money her mother stole but Hye Won stands up to them refusing to get intimidated. When the leader slaps her, she slaps him back. Shocked by her effrontery, the gang leader wants to slap her again but Tae Oh stops him. At that moment, the security comes in and the thugs disperse. Tae Oh advises Hye Won to leave home for the meantime but Hye Won refuses because if she does so, she’s acknowledging that her mother is her family.
In ha’s classmate informed him about what happened to Hye won. In ah is worried and calls Hye won but she doesn’t pick up her call. He starts searching desperately for her. Meanwhile, Tae Oh ponders over what Hye Won said. He finally realizes his feelings for her and starts running to get back to her. But In ha finds Hye won first in an empty class room and kisses her. Tae Oh unfortunately sees them and is heartbroken. While she’s kissing In ha, Hye won notices Tae Oh from the corner of her eyes and watches in defeat as he leaves.
