Takumi, a childhood friend who lost her father, lives with her mother, Ayaka. Ayaka is very different from her mother. It was always beautiful and I was thrilled inside. One afternoon, I went to Takumin's house to return the game I borrowed, but there was no response. When you go around the back, you can see Ayaka through the glass. - When I looked at it for a while while thinking that I shouldn't do it, Ayaka started to do it alone ... I couldn't stand it, so I went up and pushed Ayaka down.
