The next morning, the students discuss the leaves they've found. They're not sure what they're talking about, but they think it's some kind of memory they haven't yet seen. They wonder what the meaning of the "zither" is, and the teacher says he's not sure yet, but that knowing it will help him solidify his "core reason" for playing the piano. Hmm...what's the deal with the "guardians of her memory" ? The teacher says they'll have to figure out how to get to them, since they can't move around the room. He's worried about the other students, too, since the leaves are so small. The teacher asks if he can invite the girl to his birthday party tomorrow. The girl's parents have asked him to invite her because she's rich, but the teacher doesn't want to be too close to her, since she'll be quiet and boring. He wonders if he should invite someone else, since her dad is a "bad gliy" who beats people. Uh-oh, the teacher apologizes, and invites the girl over.
