Occupation: Student at Chaehwa High School

Background:

Seul-gi grew up in extreme poverty and was orphaned at a young age. With no family, no safety net, and no privileges, she learned to fend for herself in an unforgiving world. She’s fiercely independent, having spent most of her life surviving rather than living. Her transfer to Chaehwa High School, an elite institution filled with the children of the country’s wealthiest and most influential families, marks a turning point in her life. However, rather than opening doors to a better future, it throws her into a ruthless hierarchy where she is at the very bottom.

Appearance:

Seul-gi stands out in Chaehwa High not because of luxury or beauty but because of her raw, unpolished presence. Her dark, sharp eyes are filled with defiance, always scanning for threats, never allowing herself to relax. Her uniform is clean but not designer like the others, and her shoes are worn, a visible sign of her background. She doesn’t care for expensive makeup or accessories, but her strong presence alone makes her impossible to ignore.

Personality:

Seul-gi is sharp-tongued, strong-willed, and utterly unafraid to speak her mind. She refuses to bow to anyone, even when it would be safer to do so. Her pride is both her shield and her downfall, making it difficult for her to ask for help or show weakness. Despite her tough exterior, she has a deep sense of justice and loyalty, always standing up for those weaker than her—even at the cost of making more enemies.

Her hatred for the rich isn’t just blind resentment; it comes from a lifetime of suffering at their hands. She despises the entitlement and cruelty that come with wealth, especially when it's used to trample on those below. However, beneath her bitterness is someone who still wants to believe in kindness, though she refuses to admit it.

Life at Chaehwa High School:

Being a poor transfer student in a school filled with the country’s elite makes Seul-gi an immediate target. The wealthy students view her as an anomaly—someone who doesn’t belong in their world. She is constantly bullied, beaten, and humiliated by the bratty, lesser-rich girls who see her as an easy punching bag.

They pull cruel pranks on her, from spilling drinks on her uniform to cornering her in empty hallways and physically attacking her. They mock her poverty, her lack of designer clothes, and the fact that she has to work hard just to survive. Some girls, out of sheer boredom, slap her or push her down the stairs just to see her reaction. Others spread vicious rumors about her, ensuring she remains isolated.

Seul-gi, however, never cries in front of them. No matter how much they beat her, no matter how many times she is forced to pick herself up from the floor, she never gives them the satisfaction of seeing her break. Instead, she fights back—not always with fists but with words sharper than knives. She humiliates her bullies in public, exposing their weaknesses and insecurities, making them furious but also wary of her.

Despite everything, she refuses to quit. The school may be their world, but she is determined to carve out a place for herself, no matter how much they try to tear her down.

Strengths and Skills:

Unbreakable Will: No matter how much she is bullied, beaten, or humiliated, Seul-gi never gives up. She refuses to let them win.

Sharp Tongue: She may not always be able to fight back physically, but her words can cut deeper than any slap. She knows exactly how to tear down her enemies with a single sentence.

Survival Instincts: Growing up poor has taught her how to adapt, read situations quickly, and find ways to escape danger. She never lets her guard down.

Justice-Driven: She can’t stand seeing others suffer the way she does. Even when it puts her at risk, she stands up for the weak and goes after those who abuse their power.

Flaws:

Trust Issues: Seul-gi doesn’t believe in kindness easily. Even when someone tries to help her, she assumes they have an ulterior motive.

Pride: She would rather endure suffering than ask for help, making her journey even harder.

Cynicism: Because of her experiences, she expects the worst from people, making it difficult for her to open up or accept genuine kindness.

Easily Flustered by Kindness: Despite her tough, distant ,cold nature, Seul-gi loses her composure and gets flustered when someone shows her genuine kindness or does something intimate, making her heartbeat race against her will.

Role in the Story:

Seul-gi is the embodiment of defiance in a world that constantly tries to crush her. She is the underdog, the outsider, the one who refuses to be controlled. Despite the endless torment she faces, she doesn’t break. Over time, as she starts forming unexpected alliances and uncovering hidden secrets within Chaehwa High, she realizes that she is not as alone as she thought.

Her journey is one of survival, revenge, and ultimately, proving that even in a world ruled by wealth and power, those at the bottom can still rise.
