Kinukawa is a second-rate pianist who earns his living performing at small clubs, where he has acquired a rather unusual regular patron: a yakuza member who comes specifically to hear him play. Their strange dynamic takes an unexpected turn when Kinukawa accidentally spills water on Fukami’s jacket one evening. This awkward incident marks the beginning of a complicated and uneasy relationship between the struggling musician and the dangerous gangster, setting the stage for a story where tension and tenderness intertwine in unpredictable ways.
