In the tropical city of Miyazaki, there is a mysterious piano placed in a bustling corner of the city. Anyone can play this “street piano” freely at any time. An elderly man waiting for the bus plays a children's song with one finger, while a young man plays the theme song from a drama. Since it was placed there three years ago with the aim of bringing vitality to the city, this spot has quietly gained popularity. People gather to applaud the music played by a man who has been visiting daily since the piano was installed and practicing on his own. What are the feelings of the people reflected in the piano melodies echoing through the streets?
