Hitomi (43 years old), 24 years of marriage, 1 child. My husband, who was three years older than I knew when I was a student and got married at the age of 20, works for a major general contractor. Communication with her husband, who has been working abroad for a long time, was insufficient, and eventually she became sexless. It's more like a business partner than a couple. I was swayed by the distorted view of love of my son who grew up without knowing his father's love, and I could not talk to my husband about the trouble with my father-in-law that occurred after that. Tired of a lonely life, a married woman embarks on a journey with a man who once had a physical relationship.
