Yū, a young musician trying to find his voice through guitar and online performances, lives a quiet, uncertain life shaped by creative ambition and emotional restlessness. His routine shifts when Mikio, an older man who records everyday life on his smartphone, enters his world. What begins as a tentative connection gradually deepens as they start living together, sharing small domestic moments that blur the lines between documentation and intimacy. As their bond grows, a single kiss becomes a defining memory—tender, unresolved, and quietly transformative. The film reflects on how love lingers through fragments of memory and how “the way home” is not always a place, but a feeling tied to someone who once changed you. Intimate and introspective, it explores connection, age difference, and the fragile imprint of first love.
