Wooin seems to enjoy the thrill of the fight and when his orders go according to plan, he is also an adrenaline junkie as he rides his bicycle off the roof of a building. He was also supposed to get turned on by seeing how desperate someone was. People would call him a sadist.The Joker is the undisputed champion of the underground cage fighting scene. He is mostly seen working together with Wooin and is often seen together. They are considered good friends.
