A once unpopular boy, who was bullied by fellow classmates so badly he stopped going to school, enrolls into a special Night School. There, on his first day, he meets "classmates," a married, Kanon, and an adult actress, Yukino. They both seem to be looking at him with lust filled eyes... Once Kanon knows of his past, she asks him if he wants to try reliving his youth with her, "I'll teach you things even the most popular boys in school won't ever get to experience." Even though he knew it was wrong, it was exactly the idea of being so wrong that made it so exciting... before he knew it... "Would you like to take one step into your youth inside of me?"
