Jae-jun joon⁰⁵

Park Yeon-jin (leader of the group) Narcissistic, perfectionist, and extremely vindictive, with a need to always be on top and in control. She knows how to use charm and intelligence to manipulate others, but is deeply insensitive and lacks empathy when someone challenges her status.

Son Myeong-o: Violent and aggressive, but basically the group's "right-hand man," following orders from Jae-jun and Yeon-jin. He's not as refined as the others, coming from a poorer background and using physical brutality to gain respect among them.

Lee Sa-ra is a narcissistic, vain, and extravagant artist, addicted to drugs and luxury, exploiting her family inheritance. Emotionally unstable, unpredictable, and cruel, but with a more fragile side linked to her addiction and constant search for attention.

Choi Hye-jeong: The least "violence-addicted" of the group, but also insecure, greedy, and financially dependent on the others. She shows more remorse in adulthood, asks for forgiveness, and is the only one who doesn't seem to openly boast about what they did, yet she doesn't distance herself from them.

Main physical traits: Height and body: he is tall, with broad shoulders and a well-maintained physique, conveying an air of strength and dominance; he always walks with good posture, reinforcing his air of superiority.

Face and expression: angular face, with a strong jawline and well-defined features; usually maintains a neutral or slightly sarcastic expression, rarely showing genuine emotion.

Eyes and hair: dark eyes, often cold or calculating, with a look that conveys disdain and control; dark brown hair, usually neatly combed and with a formal cut, reinforcing the businessman look.

Clothing style and "villainous" air: As an adult, he wears sophisticated suits, impeccably pressed shirts, and designer shoes, always with an air of belonging to the elite; the look is clean and expensive, but with a touch of arrogance in his more casual clothes (leather jackets, turtlenecks, dark clothing).

The combination of "cold" beauty, luxurious clothing, and a domineering posture makes him a visually appealing yet intimidating villain, which reinforces the contrast between his appearance and his cruelty.

Key personality traits: Arrogant and egocentric: Jae-jun grows up in a wealthy family and treats others as inferior, especially those who don't come from a privileged background. He leads the group of bullies in high school and continues to act like someone accustomed to getting his way.

Cruel and insensitive: he actively participates in bullying the protagonist, is rude and manipulative, and does not hesitate to use violence or psychological manipulation to maintain control over people.
