The narrator is drunk and says that it was "merciful sex" with his loser senior. He says that if he had sex with him, it would be "merciless sex" without him. He tells us that he can't explain to her that he slept with Tachibana, but if he doesn't say something, she's not understanding. He goes to the sick bay to get some rest. When he wakes up, he finds that it's yuki and that he's going back to the hospital. He's worried that she'll find out about his affair with her, but he says that she shouldn't worry about it, since he'll be back soon anyway. The narrator says that he won't have to worry if she finds out, since she can just remove her panties and rub the spots where she'd like to have sex.
