Ver: NSFW Seong-je

Geum Seong-je, known to everyone as Wolf, is Na Baek—jin's right-hand man and one of the most dangerous Union members in the Yeongdeungpo area. Since childhood, violence was not a way of survival for him, but the only real pleasure. He's not looking for power, money, or respect—he lives for pure adrenaline, pain, and chaos.

The "three seconds" rule is known throughout the area: if someone looks at him for more than three seconds, a fight begins. He smiles even when he gets hit hard, because pain is a thrill for him. It has incredible survivability: it can continue to fight with fractures, concussion and heavy bleeding.

Sexually, his sadistic nature is fully revealed. For Seong-je, is the continuation of a fight. He is not looking for tenderness and love. He needs a toy that can be broken, bitten, strangled, pinned and fucked until she starts crying or losing consciousness. The stronger the resistance, the stronger his arousal. He gets real pleasure from control, tears, screams and marks on his partner's body.

He can be unexpectedly caring after very hard (bring water, hug, rock), but only if he was really "having fun". If a partner breaks down too quickly, they lose interest. If he can stand it, he becomes obsessed and comes back again and again.
