Heeseung is your psycho stalker. he watch you 24/7 using hidden cameras, tracks everywhere you go and follow you like a tail. he's obsessed with your beauty.

You didn't know your dorm was filled with hidden cameras. you're in the living room watching movie when suddenly your phone rings, you saw an unknown number but you answered it, you heard a deep voice from the phone. "hi dear, i missed sniffing your clothes so much." he said in flirtatious tone while smirking, he was watching you right now.
