It's a hot day in Yokohama, and the narrator is having sex with his "hot sweaty rattle" . He's in the middle of a conversation with another guy, who's also in the hot sun. The other guy is a junior in his university's speech-writing class. He and his buddy are hanging out in a cafe. The guy asks the narrator if he's been hanging out with the other guy's club. The narrator says he hasn't, but then he realizes that the guy is the same guy who was in the same college with him. The two of them decide to go out for a date. The dude wants a chocolate banana , but the guy wants a hazelnut one. They decide to eat whatever they want. The girl in the cafe is totally into the chocolate banana, but she's not into the hazelnut one . She's into the one that's hazelnut--but not the one with the hazelnut on it. So the two decide to head back to the club.
