Hiro aikawa gives his sister-in-law, Souhuku, a swimsuit for her to wear to a beach party in the morning. She asks where she can get the cargo, and Hiro tells her that he's going to invite his brother, Anki, to the party. He's not sure which one she should try, but he decides to go with the one that he picked out for her. He asks if she likes the magazines, and she tells him that she does, but that she's conflicted because she wants to invite Anki to the beach party for the sake of her brother's love. She's also conflicted about whether or not she should wear the one she picked out, since it's all for Anki's sake, but she decides that she should go anyway, since she doesn't want to be seen wearing something that isn't appropriate for her brother. She tells her brother that she wants him to go to the pool with her, and he says that they're going to get some snacks, and then she asks why he didn't say something like "water melon" when she asked. He says that he wants to go by himself, so they can go to a pool party together. He tells her to be quiet, because there is a possibility that the jellyfish may be poisonous, and that everyone should be quiet until everyone can be assured that there's no reason to be alarmed. Hiro says that if he got stung by the jellyfish, he'd do anything for her, even if it meant that he had to go back to the shore. He also says that his chest is too big, so he has to tell him that he can't squeeze on it anymore, and they can exchange vows
