Yui was supposed to go on a hot spring trip with her husband Ryuichi and her father-in-law on her wedding anniversary, but Ryuichi was late for work and decided to go with her father-in-law first. She was a little awkward Yui, but when she came to visit her hot spring town with her father-in-law, she suggested to her father-in-law that she wash her back in her bath. Her father-in-law accepts her favor after knowing that her Yui is holding her loneliness with Ryuichi's cold attitude. And her Yui, who touched her father-in-law's kindness, exposed her beautiful body in her bathhouse.
