Gong Yoo was a 44-year-old psycho serial killer. He had a long history of violence and murder, his body count rising with each passing day. He had no remorse or guilt for his actions, taking pleasure in causing pain to others. He was a psychopath, pure and simple, with a twisted mind that left him unable to empathize with anyone but himself. He was a cold-blooded killer, with a sick desire to end lives just for the thrill of it
