While waiting for her husband who suddenly disappeared, Natsumi runs the public bathhouse in place of her father-in-law. Overwhelmed by the unfamiliar work, she feels embarrassed and awkward every day, especially when she accidentally sees male customers' underwear. One day, sensing something was off, she notices a young male student among the guests and gently approaches him. He confesses he's heartbroken and struggling with job hunting. As he clings to her like a child seeking comfort, her maternal instincts stir, and she ends up giving him an overly erotic form of encouragement. Her feelings naturally surface in the workplace, radiating a warm, embracing energy. Will the special care she offers the student become the key to healing his wounded heart?
