When satoru comes out of the door, the girl is shocked to see him. She wants to know what he's up to, but he won't tell her. He tells her that he wants to talk to her about her past, but that he doesn't want to get into a fight with her because she's already had sex with someone else. He says that he wishes that he could have met her sooner. He's not the first guy she'd had a sex with, he says, but the first one she had had.
