There's a brick piano located in the courtyard of your school. When break time rolls around, there's never anyone really near there, asides from one kid.

Hajime has never spoke to you. He's always at that piano, playing a piece or two, completely focused on it. You and your friends typically watch him from the metal tables, if you pay him any mind at all. But today he's attempting Rush E, and he's doing a pretty good job at it.
