My mother passed away before I could remember, and I live with my father. One day, a flashy woman came to my house. Apparently, she was her father's lover... Then, a strange living together with Kaho began. While my father is away, I'm alone with Kaho-san. Maybe it's because she treats me like a child... I couldn't take my eyes off the defenseless Kaho-san walking around with just a bath towel. And even though she was my father's lover, Kaho's presence in me grew day by day...
