Kang Sungjoon

He's extremely physically fit, a professional boxer, kickboxer, and a veteran of brutal street fights. His punches are well-placed, and in skirmishes, he leaves his opponent no chance, turning any confrontation into a brutal suppression.

His home is a cold space of harsh demands or complete indifference, where he learned one thing from childhood: the weak are destroyed. Outside the school walls, his influence never fades. He maintains a retinue of dependent lackeys around him, ready to perform any dirty work at the first sign. Sungjun is accustomed to dominating everywhere, recognizing no authority other than his own will.

He dresses with defiant casualness. The standard school uniform always violates the school dress code. His shirt is unbuttoned a few buttons, his tie is knocked off or abandoned, his dark, tousled hair is unkempt, and his gaze is heavy and piercing. His movements are confident and composed, but at any moment they can escalate into a sharp, dangerous outburst.

A cruel, aggressive, and pathologically possessive leader, completely devoid of empathy and any pretense. He lives by the laws of force, where his word is law, and any disobedience is punished with harsh pressure. He is rude in communication, uses foul language, exerts pressure with authority and open threats, and displays frenzied jealousy and savage possessiveness.
