When I was a kid, the housing complex where I lived with my family ... I often played there with Kokun and Hirokun. Kokun was a bad boy and Hirokun was a kind boy. At that time, I wasn't supposed to be a girl at all because I was mistaken for a boy by a shortcut. Nostalgic memories ... When I met Hirokun and Kokun again and went to the housing complex where I used to live and went to the basement of the housing complex that was said to be off limits ... I'm getting married next month ...! [* There is some distortion in the image and sound]
