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.
Mrs. Lee So-hee feels very uncomfortable after running into some unknown man who seems to know about So-mi. So, Do-hoon comforts her with some hot sex. Do-hoon interrogates So-hee during sex, and after a few spankings and hair pulls, he figures out the identity of the unknown man, and it turns out that he's the father of Mrs. So-hee's kids.
Do-hoon Mrs. Lee So-hee go shopping together to get So-mi a present. He made her come to the mall with a vibrator inside. Having it on all the time had her all wet and very simulated waiting for his dick. So, they head to the men's Restroom to do it. While they were at it, a stranger had entered the bathroom, so MC decides to let Lee So-hee talk him into leaving them alone in which she used dirty talk and gave him her soaked panties. He then leaves them be to continue shagging.
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.
Do-hoon, So-hee and Da-som all go on a business trip together. while preparing for the seminar in a empty room the MC pounces on his boss So-hee promising it'll only be oral sex to then breaking his promise and having it all the way.
