4 & 6(4と6)

Lira, a girl who has moved from Osaka to Manazuru, a port town in Kanagawa, due to family reasons. She despairs in her life and throws her violin which she has dedicated everything, into the sea. Coincidentally, it was Junpei, who picks up the violin. A dreamy boy who was always strumming a tattered guitar with only four strings in the harbor. Junpei finds a video of a transfer student, Lira, playing a violin on the internet, and asks Lira to teach him the guitar because "the stringed instruments are the same." Junpei always talks brightly about the future, but somewhere in his heart he gives up that he has to take over the dried fish shop of the family business eventually. But still, Junpei keeps having passions and desires for music. His passions awakens Lira’s feelings of passions for music even aching in her heart, she feels sympathizes with Junpei, and her feelings for the abandoned violin gets stronger and stronger.
