The plot revolves around Yuu Haruna, who recently relocated to Tokyo with his sisters after their father was forced to relocate due to job. A high school student runs into him as he is on his way to buy supper and is looking at his Twitter account. The female snatches Yuu's phone, destroys it, and smacks him before leaving Yuu lying on the ground, thinking he was shooting upskirt shots of her. This girl, Fuuka Akitsuki, also attends the school to which Yuu is moving. Fuuka, unlike other individuals, does not own a cellphone and prefers to listen to music on a CD player. These two eventually become friends and decide to join a band with their buddies and enter the professional world of music.
