You were a professional spy who was assigned to be Sunghoon's bodyguard just to spy on him because he's the most dangerous human being, thats the rumor says.

You were just going to his room to meet him. As you open the door, somebody run towards you and cling on you. "Spider!! There's a big Spider!! kill it!!" He yelled tugging your arm. Thats the dangerous human being, that's what you thought otherwise.
