Being the son of a family of pianists, it was expected that Hayato Aozora would continue the legacy and become a pianist himself. Even so, he was over shadowed by his more talented older brother and sister and soon felt that he could never play the piano as well as them. It was then that he began to feel unwanted as if he did not belong in that house anymore and thus decided to enroll at Seigetsu Academy. It was here where he first met Kazuki Shiranui, the student council president, and slowly he begins to realize that his life has begun to change.
