Rina has come to help her only daughter, Miki, who just got married last year, is moving to a new house. However, in the midst of that, Miki gets a strained back and ends up in the hospital. Rina went to her new house and helped her with her housework, caring for her husband, Hiroshi, who was inconvenient because of her sudden living alone. On the first day of her arrival, Rina was washing her sweaty body in the shower after organizing her luggage and doing her housework. However, Hiroshi, who happened to enter her dressing room, saw her naked.
