Intro. Tadao has autism, doesn't go to school, has no friends, and just stays in the room playing games and masturbating all day. Ayaka's husband goes away on business and only comes back a few times a year. Her husband handed Tadao over to Ayaka, forcing her to make Tadao work part-time. Because she wanted to talk to Tadao, wanted to be closer to him, Ayaka chose to listen to all his requests, even if it was... satisfying a boy's sexual needs...
