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. One afternoon, I visited the Takumin family in return for the game I borrowed, but there was no response. When you turn to the back, you can see Ayaka through the glass. When I was peeking for a while thinking that I shouldn't do it, Ayaka started to do it alone ... I couldn't help but went up and pushed down Yaka-san.
