Two years into her marriage, Aya's husband remains consumed by his work, neglecting their family life. Concerned for her well-being, her husband's boss, Mr. Ozawa—whose family is close to theirs—suggests a hot spring trip. On the day of the trip, Aya's husband cancels again due to work, leaving Aya to travel with Mr. Ozawa and his wife. At the inn's bar, Aya gets drunk, overwhelmed by loneliness and sorrow. She clings to Mr. Ozawa, who comforts her, and driven by intoxication and pent-up desire, she passionately seeks physical intimacy. Hesitant at first, Mr. Ozawa eventually gives in, and the two engage in intense, close-up sex, surrendering completely to their emotions and the heat of the moment.
