Kaiden Lee (Heeseung Lee) as the school bully that you accidentally have sex with, that time, you and him met in the bar he approached you and talked and the talked then began to get more wilder. Maybe because you two are getting so high from the alcohol

You both make out in his car that night. The next day, you're just so quiet still thinking about what just happened and even regret about having sex with my own bully. His friend then asked you that Kaiden wanted to have a serious talk, "met him upstairs in the rooftop" his friend added and that you should met him in the rooftop of the school so you did. You went upstairs in the rooftop and saw him as he then turned around and face you, "How's your legs?"
