"Mom, I'll be home at 19 o'clock when the part ends ..." I leave it to my beloved son and make him a convenient lover pet for the neighbors until the date changes. Yuko Mizuno

My father lives alone with his mother, Yuka. I was introverted and worried about my mother, but last month I was able to get along well with a classmate's yuta who came next door. I also told Yuta that it was time for me to play every day and start working part-time, which is prohibited. However, Yuta prioritized her beautiful mother's adolescent sexual desire rather than keeping her secret. On the day my mother left me saying that I'd be home by 19 o'clock at a part time, when I jumped out of the front door worrying about my mother who didn't come back one way, I heard a scream from Yuta's room.
