Kimio Suga hides in a locker when the girls' changing room fills up around him, and classmate Nozomi Komine finds him there and covers for him instead of turning him in. Nozomi turns out to live across the way in the same building, and that night she texts him her price for silence: the two of them showing each other their bodies through their windows whenever she says so. Kimio plays along rather than lose his place at school.
