My mother passed away before I could remember, and I now live with my father. One day, a flashy woman came to my house. Apparently, she was her father's lover...and then a strange cohabitation with Kaho began. While my father was away, I was alone with Kaho. Maybe it's because she treats me like a child...I couldn't take my eyes off Kaho, who was defenseless as she walked around wearing only a bath towel.
