"Yuri" has a secret that she can't tell her husband. It was an encounter with an elderly man "Kato" who lived in the apartment next door. The love affair started with lightheartedness, but eventually became an inseparable relationship. "Yuri", who wanted to have a child even though "Kato", who was confused about vaginal ejaculation, probably had a low sense of chastity and closed her eyes with a happy expression.
