Married for two years. Her husband is busy with work and, even on days off, comes home exhausted, paying little attention to his wife. At the same time, he shows intense possessiveness about her going out, causing her to stay confined at home. Feeling unvalued and neglected, her loneliness and longing deepen. During a trip, she opens her heart to a man she meets for the first time and surrenders herself to him. Though shy at first, her expression gradually fills with pleasure as she becomes overwhelmed by sensation, feeling a deep inner release. Just as she surrenders her body to the hot spring waters, her heart and soul are stirred throughout the journey. By the trip's end, she experiences a new emotion she has never known before.
