Momoha, a young wife who remarried her middle-aged husband, who runs a company, decided to go on a weekend trip to a hot spring with her family of four, but she seemed somehow depressed and sighed softly in the passenger seat. Her husband's family is financially well off, but Momo's desires as a wife and mother-in-law, as a woman, have been building up in her body and have not been satisfied. During the trip, this young wife made a mistake with a simple country boy who kindly spoke to her.
