Takumi, a childhood friend who lost his father, lives with his mother, Ayaka. Ayaka is very different from his mother. She is always beautiful and I was excited inside. One afternoon, I went to Takumi's house to return a game I borrowed, but there was no response. I went around to the back and saw Ayaka through the glass. I knew I shouldn't, but I looked at her for a while and Ayaka started doing it by herself... I couldn't stay sitting still, so I went in and pushed Ayaka down.
