Shuhei Amamiya transfers into Kai Ichinose's elementary school. As an aspiring pianist, he's shocked that Kai has no teacher after hearing him play.

To Ajino, who hurt his musical abilities in a car accident, meeting Kai seems like fate. But Kai just wants to be able to play a certain Chopin piece.

Ajino sets a Mozart piece as Kai's entry for the contest, but Kai worries that he hasn't found his own style of playing. Shuhei is favored to win.
