It all began because he didn’t want her to see the MinYeong posters. The interruption leads them back to her place where she wears her old school outfit.
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.
Jun-Ho Kim and Sang Hee Cha found it difficult to talk freely after having sex. While they were cleaning a building, Jun-Ho couldn't stop staring at Sang Hee's body. She noticed, which made her uncomfortable but also aroused. Unable to take it anymore, she confronted him. He asked if she remembered what happened between them and then kissed her. She didn't push him away because she liked it, though she warned that someone could walk in. He was desperate for her, fingered her to orgasm, and then pulled down her pants and penetrated her. Despite thinking she should say no, her body gave in, and she was overwhelmed by pleasure she had never felt before, realizing there was no going back. After he creampie her, they cleaned in silence.
Now, Jun-Ho knew she wouldn't avoid him anymore. Whenever they were alone, he would have sex with her in various places like the cleaning company's meeting room or an empty studio apartment, usually when their colleague Soo-Ah had gone home. Sang Hee would always start by saying no, but he would always convince her to continue. Jun-Ho was happy to finally have a chance with the woman he admired.
