The narrator tells us that he's made his girlfriend's fingers "so sorry" that they'll feel "unpleasant like that" . He also says that he wrote her a love letter and put it in the bag with the panties so that she'd know that he was serious about her. The narrator then tells us how embarrassing it is to wear these sexy pants all day. He says that if he doesn't wear them, then Mr. Tsuji will have to watch the sex scene in the movie and that'll be even more embarrassing than wearing them all day long. He's so embarrassed that he can't even go to school because of it.
