In his last year of middle school, Hajime comes across an aspiring violinist Ritsuko Akine, who loves to play in the infirmary. After meeting a few times, and Hajime showing interest in her 'horrible' playing skills, he is set up to teach her by a teacher. This teacher later pushes him to regain his talent by joining the orchestra club at a prestigious high school, which have won national competitions eight years in a row. Once persuaded, Hajime and Ritsuko manage to get accepted to this prestigious school after diligently studying. After his opening ceremony into high school where the orchestra club gave a performance, he has a look around the orchestra club along with Ritsuko where he meets Nao Saeki, a violin genius who has achieved the top score in many competitions and was admitted to the school purely on musical talent.
