A husband who has a wife who is about to give birth soon and is forced to live an ascetic life. I was busy with work at the company, so I asked my sister-in-law, Yumi, to take care of my wife instead of me. The defenseless appearance of Yumi was very intriguing for her husband who always spends his days in agony. One night. My husband, guided by the voice coming from the bedroom, peeped into the intense work of the Yumi couple at night.
