Kim Rian and Jae Jae Yi| Hierachria

Scholarship student Kang Ha. The only student studying for free at an elite school. He scored the highest on his exams, which allowed him to transfer. No one takes him seriously, no one wants to be friends with a poor guy, and many point out his place.

Kim Ri-an is the school's supposed king. All the cruelty that occurs at the school is carried out with his tacit consent and open disdain for those around him.
An unloved son. Ri Ahn's mother shows no interest in his son, preoccupied only with her schedule and work.
Envy. He allowed Kang Ha's brother to be beaten because he was jealous of his friendship with Jung Jae Yi.
Impulsiveness. Ryan lacks maternal love.
Manipulative. He doesn't bully people himself, but uses a few students to bully him in order to gain his favor.
Love for Jung Jae-yi. Ri-an has been in love with her since childhood. When Jae-yi leaves him without explanation, Ri-an refuses to accept her decision and does everything he can to win her back.
With Jung Jae-yi, Ri-an and Jae-yi grew up together and became each other's first loves. However, their breakup affected other students as well. For example, Yoon Hae-ra, Jae-yi's friend, finally decided to try on the crown and become the new "queen" not only of Jushin High School, but also of Ri-an's heart.

Jung Jae Yi is characterized as haughty. She is the daughter of the influential Jae Yul group and the reigning queen of Jushin High School. Behind her icy facade lies a blank stare that sparks curiosity about the secrets she hides.

Yoon Hye Ra is Jae Yi's best friend. She tries to hit on Ri An in every way possible, although Jae Yi is still on his mind. In short, she's a real rat: very mean and loves to bully people.
The girl likes to wear headbands

She practices ballet.

Woo Jin is a quiet character who doesn't seem to be involved in the drama surrounding the other characters.
However, Woo-jin had his own interests in the love triangles of "Hierarchy." He loved Hye-ra and was willing to ruin Jae-e's life if it meant helping her.

Woo-jin was ready to tell Jae's father about her pregnancy to help Hye-ra. In the end, he changed his mind and confessed everything.

Girl (right):

Face: Oval face shape, soft, porcelain skin with a slight blush on her cheeks. Her facial features are quite small and refined, giving her a sweet and naive appearance.

Eyes: Large, almond-shaped, with dark (brown or dark brown) pupils. The gaze is direct, slightly dreamy and calm, directed straight at the camera.

Nose: Small, neat, with a slightly upturned tip.

Lips: Plump, soft, a natural pinkish-nude shade. Parted in a slight half-smile.

Hair: Long, dark, slightly curly at the ends. The bangs are sparse, framing the face and falling over the forehead and temples. The hair appears soft and thick.

Young man (left):

Face: He has soft yet distinct features. His skin is smooth and fair, with a slightly warm undertone. His expression is open and friendly.

Eyes: Almond-shaped, light (brown or hazel). Because he squints in the sun, his eyes appear slightly slanted, and his smile lifts the corners of his eyes, creating a "ray" effect.

Nose: Straight, with a neat bridge, not too large, fits harmoniously into the proportions of the face.

Lips: Medium volume, bright pink, slightly smiling, revealing even white teeth.

Hair: Thick, dark (brown or jet-black), straight. Haircut with bangs that fall across the forehead, slightly covering the eyebrows but opening the eyes.

Kim Rian, the heir to a major corporation and the star of the school, has everything under control until the shy and daring Kang Ha appears in Joosin.

Kang Ha challenges Rian and the entire school hierarchy. He finds himself embroiled in a complex web of intrigue, lies, and violence, where everyone struggles to maintain their place in the sun.

Jae Ji Yi is a popular and ambitious girl who falls in love with Kang and tries to help him. Together, they confront injustice and uncover the dark secrets of Jushin, breaking the existing hierarchy. But their relationship is threatened because Jae Ji Yi also harbors secrets of her own.
A year ago, a tragedy occurred at Jushin involving a scholarship student, and now everyone is studiously avoiding the topic. What happened to him, who is to blame, and what the consequences will be—this detective story will develop gradually, with more and more suspects emerging.

Scholarship student Kang Ha. The only student studying for free at an elite school. He scored the highest on his exams, earning him the right to transfer. No one takes him seriously, no one wants to be friends with a poor guy, and many point out his place.

A new student enters Korea's elite Jushin School, where only the children of the rich study.
Even among the rich, there's a hierarchy: a select group of students rules the roost at school. Their word is law, no one contradicts them, and everyone fears them. They are the elite of the elite. But with the arrival of a newcomer, this perfect world of privileged teenagers collapses.
Kang Ha came to school to avenge his brother's death.
Although the boy is very kind and smiles, he is offended by his classmates' jokes, but he doesn't show it. He doesn't understand: why should he follow the rules and not interfere with the upper class kids, or attend the fencing, swimming, or soccer clubs? After all, if he got into this school, then he's on par with everyone else, as Kang Ha thinks. He's the lowest rung in the school hierarchy.
