It's a hot day in Yokohama, and the narrator is having sex with a girl from his class. He wants to ask her to introduce him to her friend, but he's worried that she's not going to give him a straight answer. He tells himself that he should ask her directly, since she'll be able to tell him more about her friend's personality. He's also worried that her friend is stupid and careless, so he tells her to ask him out on a date this weekend. The narrator then tells us that he'd like to ask his friend out on the weekend, but that he doesn't know how to do it. He asks his friend where she is, and she tells him that she needs to go shopping. He then tells her that he bought her a drink and some food, and that she can go home. She's all, "I'm fine, I'm just not feeling well, so I'll go with her" . She starts to cry, and when she gets home, she cries even more.
