Married to a husband who often goes on business trips, Ichika Hoshimiya spends her days at home with her in-laws. Although she really wants to have a child with her beloved husband, the frequent business trips make that desire unfulfilled. Ichika Hoshimiya has a very good relationship with her in-laws, but one thing she is not happy about is that her father-in-law often drinks to excess and takes out his anger on her mother-in-law. One night, after getting drunk, he became aroused and wanted to have sex, and being too drunk, he mistakenly entered Ichika Hoshimiya's room, and then... then... then... :))) The actor playing the father-in-law looks a bit too young, right? He doesn't really look like it at all, but according to the original name of the movie, he is indeed the father-in-law.
