In this live-action adaptation of Bambi’s coming-of-age doujin story, an unpopular loner in an adult school role-play loses his virginity to Misaki, the class idol. He briefly thinks she likes him, only to learn that the encounter was a free trial for an unlimited-sex subscription. The price is steep, so he refuses—until he sees subscribed classmates having sex with her repeatedly. He tries to stay rational and suppress his desire with porn and masturbation, but cannot forget how sex felt. Eventually he empties his savings and signs up, despite knowing that mixing business sex with genuine feelings can only end in regret.
