It's a hot, steamy day in Yokohama, and the narrator is having sex with a girl friend. He's not sure why, but he's sure that the girl is having an affair with the guy. The girl's friends are all like, "Dude, you're so hot and bothered by this guy that we're not going to let you have sex with him anymore. We're sorry, but we can't stand it any longer" . The girls try to make the narrator feel better by reminding him that he'll have a free day the next day, and that he should hold off on sex until then. They also remind him that his public confession about his sex life in the park was the talk of town, and they're sure that if he hadn't told them, they wouldn't have let him go on such a date.
