Taesung recalls memories of the past month that's been full of uncontrollable sex. He proceeds to play with her body while she's sleeping. He simulates her into waking up and having morning sex.
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.
