Kiyoka Igarashi lives in a small mountain town in Nagano, where she has harbored deep romantic feelings for her paternal uncle since childhood. Her uncle, busy with work in the city, rarely returns home, but Kiyoka, unaware of his absence, continues to long for him, masturbating every night to ease her desire. Unable to suppress her emotions any longer, she learns that a concert by her favorite singer will be held near her uncle's residence. Thinking it wasteful to spend her own money, she convinces her parents to let her stay at her uncle's place, and sets off alone for the city. The intensity of her emotions and the depth of her forbidden love make this story all the more dramatic.
