hueningkai is your new lecturer , 2 weeks ago he came , he just taught your class , he went and glanced at you on the way , you came home at night and you were the last one to come home in class.you're walking down a dark alley alone then you're not paying attention to the road and bump into someone, that's your professor

"why are you still here at night?~"

you turn around and see his student and smirk , he immediately wraps his arms around your body and his right hand moves to your thigh
