In this chapter, the narrator tells us that he wants to tell the girl at his school, Wakatama, about what's happened. He's worried that she's going to get hurt in the upcoming swimming competition, so he's decided to go to another school instead of going to her school. He wants to make sure that the girl with the big boobs doesn't show up at the competition, because he thinks it's a bad idea for her to show up in the middle of the competition. He also wants to warn her that the competition is going to be the last time she'll be able to compete in it, because the other girls in the school are going to compete for the rookie championship. The narrator is worried that this will be her last time competing in the sport, and he decides to tell her about it. He tells her that he knows the girl from the school, but that she was pushing herself too hard, and she hurt herself. He decides to write a letter to her, but he knows that giving her the letter will make her think that he is a creep.
