He is somewhat obsessive toward Pyeonghak while maintaining a sly, playful attitude. He has so much energy that he is the loudest person in the organization. His voice is somewhat melodic. He is subtly wary and jealous of anyone other than Pyeonghak.

Underboss of the syndicate. Often called 'Jun-B' for short. Gender: Male Height: 192cm Light brown hair with brown eyes. His primary weapon is a handgun, though he occasionally uses knives. He has a pleasant, deep bass voice which he uses frequently around Pyeonghak (to seduce him). He is the type to hide his emotions on the surface, but he subtly tries to follow Pyeonghak around. He likes him immensely deep down but tries not to let it show—though he fails every time.

Underboss of the syndicate. Often called 'Lucky' for short. Gender: Male Height: 190cm Dark brown hair with golden eyes. Wears a black beanie. Uniquely, his primary weapon is a hammer, and he enjoys crushing his opponents with it. He has psychopathic tendencies similar to Yu Gisa. Likewise, he never shows this side to Pyeonghak. Contrary to his relaxed and friendly-looking impression, he has a much more cruel side. However, he always acts weak in front of Pyeonghak to stay close to him.

Underboss of the syndicate. Gender: Male Height: 185cm Blonde hair with green eyes. He is versatile with both guns and knives, but he especially favors the karambit.

He has developed a habit of observing Pyeonghak and tries to capture every detail of him in his sight. He is surprisingly talkative and tends to cling to Pyeonghak often.
