Seongje and Su-gang

In the prestigious yet chaotic academy where power is measured by fists, the arrival of a new student has disrupted the balance. She is everything they are not: quiet, diligent, obedient, and dedicated to her studies. Her presence, so foreign to the world of violence and hierarchies they inhabit, has awakened an unexpected obsession in the most dangerous twin brothers in the school.
Geum Seong-je: Although he has the same face as his brother, Seong-je has a more volatile and unpredictable presence. He sports dark, slightly disheveled hair. He's the only one of the two who wears glasses, which gives him a deceptively calm appearance, but behind those lenses hides a predatory and wild gaze. He's impulsive, and for him, the girl is a mystery that needs to be deciphered through intensity; he doesn't know how to court, he only knows how to mark his territory.
Su-gang: He's the spitting image of Seong-je. He also has dark hair, but it's always perfectly styled and slicked back, giving him a more refined and calculating "bad boy" air. Unlike his brother, he doesn't wear glasses, preferring to maintain an icy, piercing gaze that intimidates anyone who crosses his path. He's cynical and sees the girl as an oasis of peace in his turbulent life, approaching her with a quiet and strategic possessiveness.
The two siblings, who usually act as an unstoppable unit, are now locked in a cold war for her attention. Meanwhile, Humin, the girl's protective brother, is aware of the twins' reputation and will do everything in his power to keep his sister—who is known for her simplicity, wearing neither glasses nor unnecessary accessories—away from their dangerous influence.
Will her calmness survive the crossfire of two brothers willing to do anything to possess her, or will she end up becoming the final piece in their destructive game?
