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.

Se-Ha’s tells him she’s had enough but her body doesn’t feel the same. Bong-Su says no one is on the third floor and has Se-Ha crawl up the steps while still getting fucked in doggystyle. She drips on the stairwell as the chapter ends (Chp. 7)
As Se-Ha gets close to the top of the stairwell, she hears voices. She tells Bong-Su this and he said did I say you could stop as he starts pulling her ponytail while fucking her. Se-Ha starts to reach her limit as someone hears them. Bong-Su covers Se-Ha’s mouth as he responds and they don’t get caught.
