The next morning, Yotsuba goes out to find his sister, but doesn't return either. Futaro wakes up to find that his sister has disappeared. He tells his sister that he's going to try to be honest with him about what happened the night before. He also tells her that she can't be like her sister, because she's wearing the same clothes as her sister. He's worried that if someone sees them together, he'll have to explain everything to them. He says that he could've spoken to her out of the door, but he knew that he was going to be ticked off. He asks if she went to the library, and she says that's where she'd gone. She also says that she didn't sleep well that night, but that she'll try to sleep well again. She asks him if he has anything to write about, and he says he has a bunch of papers to write with. He wants to go pick them up, but she won't let him. She tells him that she hasn't opened the text book in her room, and that he should just be honest about what's bothering him.
