Sang Hee was absent-minded while Jun-Ho called her a few times. He said he finished cleaning the locker area and asked if she needed help elsewhere. She said she could use the help since she hadn't gotten much done. Jun-Ho noticed her distraction and went to lock the door. When she asked why he was closing it, he came over and grabbed her boobs, saying, "So I can do this." She thought he was acting strangely all day. Internally, she wrestled with her feelings, thinking that if she truly cared about Soo-Ah, she would stop him right there, but she also felt she couldn't live without Jun-Ho anymore.
Jun-Ho remembered a new technique he had learned from Mi-seong and wanted to try it on her to see her reaction. He started performing cunnilingus on her until she orgasmed. He then immediately began to finger her again. She told him to wait, as she had just come and needed time to build up to another orgasm. He started kissing her, and she told him to stop teasing her, saying she needed him inside her. He found this adorable, lifted her leg, and penetrated her in the missionary position before switching to doggy style and creampie her. Throughout the act, she thought they should not be doing this if she cared for Soo-Ah, and that she was such a terrible mother.
After learning Sang Hee was being bullied by her brother, Jun-ho rushed to the hospital. Her brother was about to slap her when Jun-ho arrived, stopped him, and led her away. She was deeply moved, saying no one had ever helped her like that before, which made her happy. She then asked him to go for a drive.
They went to a quiet place, a spot she had gone to as a child to escape bullies. When he asked if she wanted to drive, she asked if he would just hold her. He hugged her, and when he tried to kiss her but couldn't reach, she moved in to kiss him. They began having sex in doggy style in the car, with her enjoying his warmth and feeling calm. He finished inside her, asked for one more time, and then had sex with her again in missionary, finishing inside her once more.
She realized she felt at ease with him because she could show him every part of herself, even the ugliest parts. After they cleaned up, she worried that going back would look suspicious because of the smell and asked if there was somewhere they could wash up quickly. He then drove them to a motel.
Sang Hee was avoiding Jun-Ho after smelling a different perfume on him, which made her think he was seeing someone else and upset her. Jun-Ho grabbed her, pinning her face-down, and started kissing her. He turned her on by squeezing her nipple and began to undress her. Overwhelmed, she couldn't deny him, and he penetrated her on the sofa. After they had sex and he creampie her, he wanted another round, but she was tired and asked for a break.
He said he wanted to try something new and asked for a tit job, which she had never heard of. He then asked her to lick his tip, and as she tried to lean away, he pushed himself into her mouth and came. He apologized, saying he couldn't hold back. She then asked him to do her. To tease her and make her more turned on, he fingered her anus, which embarrassed her. Both of them came, and he creampie her again. She thought he was going for another round, but he revealed he was just starving.
