A married woman's heart and body tremble on a hot spring getaway. After a decade-long relationship, she finally married, only to struggle with the gap between her ideals and reality, escaping into this journey. Arriving at the inn, she toasts with a drink in the open-air bath, covering her skin with a towel. Resisting at first, she eventually gives in to the man's advances, exchanging passionate embraces in the room. After dinner, they reenact past experiences, leading to penetration. She moans loudly, reaching climax as she rides him in the cowgirl position, forcefully grinding her hips. The next morning, entwined on the balcony, she senses someone from the neighboring room and holds back. Back inside, her suppressed moans burst free as she loses herself again and again in ecstasy. The journey ends with her mind and body utterly shaken.
