This story is about Yuu Haruna who moved to Tokyo with his sisters following the death of their father.
While he was on his way to purchase dinner, a high school student suddenly crashed into him. Yuu was mistakenly thinking the girl was taking upskirt photos of her. The girl took Yuu’s phone and broke it. Yuu then fell to the ground. It turns out that this girl, Fuuka Akitsuki, also goes to the school Yuu will be transferring to.
Fuuka, unlike most people, doesn’t have a cellphone. She listens to music on a CD player. They become close friends, and eventually form a band together with their friends to enter the professional music world. What will Yuu’s new life be in Tokyo now that Fuuka is around?
