Aono Hajime is a boy whose father is Aono Ryujin, a world-renowned violinist. Hajime, who grew up watching his father's back, has achieved good results in numerous competitions and is praised as a violin genius boy. However, for a certain reason, he stopped playing and spent his days feeling lethargic. And then, in the fall of my third year of junior high school, the day comes when the time that has stopped quietly begins to move. The trigger was to meet a girl who was a classmate. Furthermore, as he is about to go to high school, he learns of the existence of a high school orchestra club.
