A kid breaks a piano, learns to fix what he broke, and spends years earning back trust from an instrument that can't forgive him, only respond to whether he's worth playing. The music in this thing is so clean it feels like the show itself is breathing between your ribs. By the time he performs, you're not watching a recital. You're watching someone apologize to wood and strings and actually mean it.
A young boy plays roughly with a piano until it begins to make a strange sound. Once the instrument has been fixed, he promises to treat it with proper care from then on. He keeps that promise, looking after the piano and practicing hard, and years later he performs for an audience. The story is told as a single-episode music piece about devotion to an instrument and the steady work that follows a careless start.
