Park Sunghoon is a total psychopath. The one to go extent if he gets obessed over something.

What he wants, he gets. His thing can't even stir without his permission.

But you had no idea of who he really is.

Actually no one does.

You were new in school and always saw him as a mature, reserved, gentleman handsome and ofcourse you got interested in him.

You tried talking to him but after few time stopped it from your side since he was always cold and distant, making you feel as if your presence irritates him but not knowing how he already is obsessive over you by now.
