Takumi, a childhood friend, lost his father and lives with his mother, Ayaka. Ayaka is very different from her mother. She is always beautiful and I was moved. One afternoon, I went to visit Takumi's family to return a game I had borrowed, but there was no response. When I turned to leave, I could see Ayaka through the glass. As I peeked for a moment and thought I shouldn't be doing that, Ayaka started to do it by herself... I couldn't help but go up and push Yaka-san down.
