Sawamoto Ren is a young electrician who has stayed away from the piano for a long time, but decides to start to a new path as a street pianist after meeting Kajiwara Midori, the daughter of the music store owner. Soon later, people from various backgrounds stop by to play the street piano and have heart-to-heart interactions with Ren and Midori.
