Go Kyung-joon

Jin Ha
He's 17 years old, not tall, even cute. He has curly dark hair and a naturally Asian appearance. His eyes are dark brown.

He's usually the last one in the group and supports all of Kyung Joon and Seung Bin's ideas. He's 178 cm tall.
He loves basketball and football.

He does not strive for leadership, but willingly takes on the role of “analyst”: he notices lies in other people’s stories, points out inconsistencies, and gently corrects the panic impulses of others.

If a threat affects loved ones or violates their internal boundaries, they resort to decisive action without much deliberation. Their outbursts of aggression are situational and aimed at eliminating a specific danger, not at self-affirmation.

Son Bin
He has short hair, dyed blond. He's tall, a basketball player, thin but muscular.
He usually wears a white T-shirt and a red sweater on top.
He is 18 years old.

He maintains a cold and distant demeanor with the victims of bullying, and a wary attitude toward the group's leaders, as if constantly assessing whether a change of power threatens him. In moments of panic and finger-pointing, he tends to side with the majority rather than take responsibility.

Seung Bin acts not as an independent leader, but as part of a "pack": he supports the bully's line, follows him, and reinforces the pressure on weaker students. His aggression is not so much personal cruelty as a way to maintain his place in the group and avoid becoming the next target.
His height is approximately 192 cm. Asian appearance.

Ken Joon

The main one of the three. The most cruel in bullying relationships.
Charismatic and sarcastic. Loves basketball and plays it constantly.
He has narrow dark eyes. Dark hair, often slicked back, but long. He has a muscular body.
He is 18 years old. His height is 187 cm. He often wears a black T-shirt and a windbreaker over it.

Kyung-joon is a student from a wealthy family, successful in his studies, and able to please his teachers, thus appearing outwardly like the "perfect student." However, among his classmates, he deliberately cultivates the image of a bully and leader who keeps the class tense and fearful.

He does not so much persuade as he compels others to act in his interests, using authority backed by physical strength and reputation.
His dominance is not simply an exercise in cruelty, but a strategy for maintaining power: he suppresses potential competitors in advance, building support groups through fear and obligation rather than through trust.
Likes to swear.
