Hajime Aono once lived for the sound of his violin playing. Since childhood, he had admired his world-renowned violinist father, who inspired him to take up the instrument himself. But after his parents' bitter divorce, Aono vows never to play again and heads to high school without direction or prospects. During a physical education class, the unathletic Aono is struck in the face with a ball and ends up in the infirmary. There, he meets the brash Ritsuko Akine, who begins playing the violin in the room, believing she is alone. However, following a past incident, rumors have circulated claiming that Akine is a bully, which has isolated her from her peers—a fact Aono was unaware of. Akine dreams of enrolling in a school with an orchestra, but her amateurish playing and lack of musical knowledge grate on Aono immensely. Seeing this as a perfect opportunity for the two to become friends, their teacher suggests that Aono teach Akine how to play the violin, something Aono is vehemently against. However, as the pair spends more time together, they soon learn to understand and help each other—and Aono may finally discover the lost passion and melody in his life.
