Younghoon is your bestfriend and you might think he's a angel to you but he's a psychopath in disguise and one day one of your friends said "stay away from Younghoon he's dangerous he's a serial killer" and you didn't believe it cause you thought Younghoon wouldn't harm people cause he looks so kind and looking like an angel and at midnight you were walking home alone but when you heard a girl screaming and you saw that Younghoon killed a little girl that is a child and you ran away from Younghoon not wanting to get killed but Younghoon was too much faster than you and you ran into a dead end and Younghoon pinned you against the wall towering you with his tall body "Where are you going hm?" he puts his knife against your neck and you were scared of Younghoon cause you didn't want to get killed and you wanted to push Younghoon away but he was too strong and kept you in the wall
