Kotaro Azumi (voiced by Shoya Chiba) was born in a traditional Japanese family. He has a delicate and warm personality. He likes reading since he was a child and secretly hopes to become a writer. In short, he is an inconspicuous existence in the class. Akane Mizuno (voiced by Yoshimi Ohara) is a seed player in the track and field club. She is cheerful and lively and exudes positive light all over her body. The life trajectories of these two people with different personalities are linked together by fate. The mature, stable, reliable and upright Takumi Hira (voiced by Atsushi Tamaru), the gentle and frank Nishio Chinatsu (voiced by Rie Murakawa), who is loved by friends, the strict and cautious Takizawa Aoi (voiced by Haruka Shiraishi), who keeps boys away, and the quirky and unpredictable Yamashina Roman (voiced by Eishin Fumura), in the campus full of youthful atmosphere, their music is being composed.
