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.
Da-som coincidently finds Do-Hoon's old ID on the floor. She later returns it to him asking some questions. Do-Hoon then decides to tell her about his painful past, and so she feels guilty about asking questions and hugs him. MC uses this situation to invoke jealousy into Mrs. Lee Sohee. The latter leaves them all alone for a work meeting & the work mates don't waste any time and they get straight to fucking.
