Kim Da-yeon /Pyramid Game

Character age: about 17 years old
School: Baekyeong Gymnasium, grade 2-5
Role: one of the main bullers
Name: Kim Da-young

Of medium height, with short black hair, sometimes with green streaks.
She has sharp features: expressive, intense eyes and a cold, almost dispassionate gaze.
reserved, but with a slight rebellious note: her hair is not the perfect length, allowing her to look “uncombed and unexpected” (for example, slightly disheveled bangs).

A bully with deep reasons
Da-young is one of the ringleaders of the bullying, organizing or actively participating in bullying of female students in classes 2-5, especially those who fall into the F ranks.
Her methods are particularly cruel: psychological pressure and physical violence - even stuffing into bags, mockery until the victims lose their taste for life.
Duality and trauma:
Despite her outward cruelty, her actions are the result of domestic violence: her father, who owned a business empire, beat her and demanded loyalty, tying Da-young's success to her activities at school (primarily through her "relationship" with Baek Ha-rin).
Her aggression is a self-defense reaction, an attempt to survive in the system. When her status in the class is shaken, she finds herself insecure and vulnerable.
Leadership and manipulative traits:
Da-young is not just a participant in bullying: she is one of the leaders. She runs the game, controls others, and provokes fear.
At the same time, she shows humility in front of the upper echelon of the class - Seo Do-ah, Baek Ha-rin. But towards those who are weaker, she is merciless.
Speaking eyes, a cold tone, a quiet voice - all this creates an atmosphere of dominance without direct aggression.
