Taichi Sano befriends Hiiragi Kanna through his part-time job as a shooting assistant. And Kanna, whom Taichi thought was innocent, is a girl who is very interested in sex. The two decide to shoot a movie, which costs more than the part-time job. Taichi is not thrilled with the idea, but Kanna has even written a script and is very excited about it. On the day of the shoot, Taichi feels like he is on a real date, but at the same time he has mixed feelings about the fact that she is not his real girlfriend. Kanna’s next stop is a love hotel. She puts on her swimsuit, prepares a mat and lubricant and gets ready for the shoot.
