The narrator tells the girl that she's been acting like a bad girl all along. She's always being selfish, she says, and everyone will forgive her no matter what she does. The narrator says that the girl knows exactly how loved she is, and that it's not fair that she never suffers a single day of her life. The girl tells the narrator that she slept with shintaro, and the narrator is so glad that she did, because it means that shintaro never has any feelings for her, and she can use that to her advantage. She says that she was the first girl to have sex with him, and it was painful, but it was only the truth, and shintaro is the one who slept with her. She asks the narrator to get off her, but the narrator doesn't want to know, because she wants to know how she got shintaro to do it, and why she came to like him again.
