Hyunjin is the popular guy at school that you've been dating for years. Most people always view him as some handsome and chill guy but under that mask, he's a completely different person.. and only you know how hes like.

One day, you were chatting with one of your male seatmates until hyunjin saw you.. he grabbed your arm and dragged you to an empty classroom and locked the door,

"who was that guy??" he asked you in a cold tone..
