Do-Hoon sets his eyes on his target; it's Mrs. Lee So-hee's youngest daughter Han Ah-young. He invites her to talk over dinner. Before time got late, he sends her home earlier than expected & planned to meet next weekend. When the time came, they went on a date together, and at the end of the day, they go to a motel together, and they get straight to having sex where Do-hoon takes Ah-young's virginity. He starts fucking her gently and very considerately, but she wants to fuck her the way he likes (roughly) to get him to like her.
Do-hoon meets up with Seo Ye-Eun at So-mi's workplace (Caffe) to discuss the latter's relationship with her father to furthermore understand her psychology. When Do-hoon gets his answers Ye-Eun tries to leave but he doesn't let her go and punishes her for putting him in a bad situation (That's his actual reason for the meetup). It turns out that she came to the caffe commando as he asked. While they were kissing, Ah-young (So-mi's little sister) happened to be at the caffe with a friend, when she saw Do-hoon, she follows him and takes peeks at him and Ye-Eun kissing. Do-hoon notices people's noise just outside and rushes upstairs to continue humiliating Ye-Eun.
Bumsu calls Do-hoon to do some volunteer work at the church. When the former gets there, he finds his wife chitchatting with Do-hoon and senses that they've gotten closer. He later leaves them alone at the church thinking that his former high school mate wouldn't try to anything funny to his wife. Do-hoon gropes Hyuna and tries to seduce her but she isn't moved at all and leaves him. She goes back to her husband who's been waiting for long in his car, she asks him to take them somewhere nice on the weekend, but he doesn't wanna, and calls her selfish. That was the last nail on the coffin for Hyuna who's fed up with her husband's mistreatment (she recalls a memory where she caught her husband cheating on her). She storms out of his car and returns to the church in tears hoping Do-hoon is still there. When she finds him, she asks him to continue where they left off.
Do-Hoon's revenge story (as it stands): fucked and tamed So-mi's mom (His worst bully's mom) Mrs. Lee So-hee, raped his other female bully Ye-Eun and made her his bitch, and now sets his eyes on Kwak Bumsu's wife (His male bully's wife) Kim Hyuna. Do-Hoon sets things up to be alone with Hyuna in her house and pounces on her. Bumsu returns home later but Do-hoon still keeps on fucking Hyuna next to her sleeping husband.
Do-hoon makes Ye-eun attend the shoot afterparty where she drinks too much and gets drunk and dozes off. She awakens all tied up to Do-hoon who's about to torment her and make her submit to him by violating her asshole.
Do-hoon is more motivated than ever to take revenge. So, he set his eyes on completely taming his bully's mother (Lee Sohee). In a dark office room at night at their workplace, Do-hoon promises that It'd be their last night together, so he goes hardcore on his boss by putting her on a leash and enjoying a steamy night taming her and turning her into his bitch.
While still at the business trip, Do-hoon comes over to Dasom's hotel room and have his way with her and she doesn't stop him (because she already fantasized about doing it with him) and also because she initiated it by kissing him in the bathroom in a work dinner.
