It's morning in the girls' dormitory, and one of the students is having sex with another student. The other student is a girl named Yume, and she and the student are having sex. Yume tells the other student that she's having sex, too, and the two of them have sex together. The student says that he's glad that Yume didn't tell Momoka about the sex, because he'd have expected her to have found out about it. The girl says that she can't have sex with Yume because she was so angry with her, and that she doesn't know how to talk to Momoka properly. The two girls talk about how they're going to have sex on the lantern festival day, which is the day after the students return home from the festival, so they'll be able to do it on their own. The teacher sighs, and Yume says that if she can talk to the teacher properly, then they can have sex.
