The narrator tells us that he and his dad are going swimming in the ocean the next day, and that he's worried that his wife won't get along with him. He's also worried about his dad's health, which is getting worse. The narrator says that he doesn't think he'll be able to swim the next time he goes swimming, but he does want to try again in a month's time. He asks his friend, sanami, if she's sick, and she says that she is, too. She complains that her wallet is missing, and he says that it was he who stole it, not her. He also says that the class is "full of idiots," and that the police are useless. He says that if he didn't steal the money and burn the wallets, everyone would assume that he did it, and then he'd be blamed. He wonders if his wife is going to be happy with what he did, or if she will be too upset to be angry about it.
