Married woman Marina, who just tied the knot with her husband last month after a workplace romance, has been enjoying a peaceful and happy life together. One afternoon after school, her husband witnesses delinquent student Yamamoto bullying classmate Kobayashi. Enraged by Yamamoto's behavior, he strikes him on the spot to put an end to the incident. The next day, Yamamoto shows up at school with a bandaged arm and confronts Marina, accusing her husband of physical assault. Desperate to calm him down, Marina tries reasoning with him, but Yamamoto coldly declares he'll drop the charges only if she "personally bares her body and shows him her breasts." His words cut deep, and Marina feels their tranquil life beginning to crumble as a new storm rolls in.
