After losing her husband, Monami lives alone with her son. Struggling to make ends meet on her part-time income, she begins falling behind on rent. Kenji, the landlord's son, notices her striking beauty and uses the rent collection as an excuse to get close to her. Rather than simply collecting payments, Kenji—along with his mischievous friend—becomes increasingly drawn to Monami's voluptuous, alluring body, drawing nearer to her under false pretenses. As harsh reality and raw desire intertwine, a provocative story unfolds between them.
