Si-Yun is desperate to get out & meet up with Ji-Hyeon, but Song Yeonsun stands in his way & won't ever let him go past her. He begs her but she's not impressed so his only other option is to use violence, little did he know that Yeonsun is a retired martial arts promising talent. He gets put to the ground quite easily. In order to free himself from her grip, he resorts to touching her in her most private parts & he succeeds in doing so he threatens to pounce on her, the only problem is that he made things worse by awakening something in her that is way harder to get from. She takes up his words against him and pounces on him saying: "Don't worry young master, I'll make you feel good".
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.
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.
