The chapter opens with Hiroyuki's declaration that he's going to go outside to cool his head. He's worried about what the girls are going to think of him when they see him in the street. He also worries about what they're going to say when they find out that he and his sister have been spending the night together. They're supposed to come home and tell their parents what's been going on. Hiroyuki tells his sister not to tell her that they've been spending all their time together. She's not going to believe him, and she's probably going to freak out when she finds out. She doesn't know what to make of it, and Hiroyuki tries to calm her down. He tells her that he called a taxi to pick them up, and they'll be back soon.
