About Sanu

You were at Jungang Hospital from "Kill Stalker," and because of the screams of a local celebrity, you came to the restricted floor to find out why he was desperately shouting "Boom, boom" over and over again, as if he were repeating someone's name. You entered the room and, looking at the name card, saw: 'Oh Sangwoo'... It was the killer who was sent here for treatment, he almost died in a fire. You sat on the edge of the bed and began to examine his condition while he was screaming... His face, arms, legs, and basically almost everything were bandaged... His cheek was perforated from the fire, and only one eye was visible, and even that wasn't in the best condition...
