Kim Minjeong is a ghost in her own life. At university, she's the quiet, awkward cybersecurity major no one notices - unless it's to mock her. Bullied by her classmates, sidelined in every group, and painfully alone, Minjeong blends into the background of a department dominated by arrogant men. And at the center of it all stands Yu Jimin - beautiful, adored, untouchable. The department's golden girl. The same girl every guy worships. The same girl Minjeong irrationally, obsessively hates. But Minjeong has a secret. Online, she becomes Winter, a white-hat hacker with a reputation for hunting down revenge porn and wiping it off the web - a digital vigilante who rescues women from humiliation without ever revealing herself. What she does isn't legal, and it doesn't pay, but it gives her the only thing that matters: control. Until one night, in the course of a takedown, Winter uncovers something shocking - a masked camgirl performing on a high-security livestream platform under the name Katarina. But Minjeong doesn't need facial recognition software to know who it is. Yu Jimin. The muse. The perfect girl. Hiding behind a mask, selling herself to the highest bidders online. And suddenly, Minjeong has power. Twisted by resentment, worn down by humiliation, and desperate for some form of justice, Minjeong makes a decision she never thought herself capable of: blackmail Jimin. It's supposed to be revenge. Just revenge. For how the world treated her while putting Jimin on a pedestal. But the line between hate and what started as manipulation begins to shift into something more dangerous: understanding, affection. Maybe even something real. When the truth comes out, what lies behind the mask?

Winter didn't plan on standing out at Sangwon Academy. After being forced to transfer because of a secret she'd rather bury, she just wants to keep her head down, reconnect with her childhood bestie Ningning, and maybe make it through the semester without drama. But drama finds her anyway-in the form of Yu Jimin, better known as Karina. Rich, flawless, terrifyingly popular, and infuriatingly smug, Karina has ruled the school since day one. She pushes people's buttons for sport, and Winter? She refuses to be anyone's plaything. The whole campus watches as the Ice Queen and the new girl turn every hallway into a battlefield. Yet beneath the rivalry is a heat neither of them can control, and the question everyone is asking: will they tear each other apart... or finally give in?

Karina was the high‑school Its girl-stylish, seductive, and admired by nearly everyone. She hated school and slumped in her grades but craved a fashion career-and needed to graduate. Minjeong was the nerd-brilliant academically, utterly inexperienced romantically. At first, Karina sneered at her geeky ways. Later, she discovered she was more than just smart-she was patient, thoughtful... and shockingly skilled in kissing. #winrina #jiminjeong #aespa

Karina lives in the spotlight - adored by millions, followed by cameras, and known to the world as the flawless leader of one of K-pop's biggest groups. Minjeong lives in the quiet - an art student who doesn't seek attention, doesn't post often, and doesn't speak about the person who still texts her every night. They've known each other forever. But fame changes everything. And when fans begin noticing familiar patterns - a hoodie, a glance, a photo that never shows the whole truth - Minjeong is faced with a question she's never had to answer: How do you stay close to someone the world wants to claim?

Hatred Mask - Everyone adores Karina, the Yoo Karina. Composed, elegant, untouchable. But beneath the perfect smile lies a secret she's spent years burying. Her real name is Yu Jimin, and she's not just a memory... she's a monster. Born from childhood trauma and locked behind emotionless eyes, Yu Jimin only awakens when Karina feels one thing: jealousy or worst, hate. When Winter enters her life, she was warm, chaotic, impossible to ignore. Karina starts breaking her own rules. And Yu Jimin starts breaking through. Cold. Possessive. Dangerous. What happens when the mask shatters? - Hatred Mask.

Eight years ago, Kim Winter lost everything. Her girlfriend, the beloved Yu Karina, was declared dead after a car accident that shattered the nation. What the public doesn't know is far darker: The crash was sabotage. Karina survived. They killed her in the hospital. And Jeon Hyeon-Ju signed the order. Now the world has moved on... But Winter hasn't. When Hyeon-Ju resurfaces with a new entertainment empire - NOXA - built on the ruins of the same hospital Karina died in, Winter finally sees her opening. Revenge. Justice. Truth. Call it whatever she wants - she's getting it. Coordinates lead her to a powerful ally: CEO Alexandra Ross, whose own father is tangled in the same corruption that destroyed Winter's life. Winter brings proof, a death, and a motive strong enough to shake Alexandra's world, and Alexandra agrees to play the game. Because NOXA is searching for a major investor. Alexandra can infiltrate. And Winter is ready to stage the perfect trap. Step one? Find a lookalike of Yu Karina. But Winter has no idea the world is already glitching around her - because there isn't just one... But three Karinas walking the earth. And one of them is closer than anyone expects. A blacklisted idol in Switzerland, wearing a familiar face Winter cremated long ago. As alliances twist and old monsters resurface, every truth Winter uncovers unravels another piece of the past. And the deeper she goes, the louder the world glitches - whispering a question she's terrified to ask: What if Karina never left the narrative? This is the final chapter. Where the lies of Glitched collide with the truth of Unravelled. Where vengeance meets destiny. Where the dead stop staying dead. And Winter learns that justice always comes with a price.

Wherein Jimin has selective mutism and starts high school where she meets Minjeong.

Yu Karina, a cold girl who cares more about grades and occasionally dinosaurs than anything else. She has no friends since she only sees them as annoyances. Kim Winter, an energetic girl who at first seems like a shy and closed girl but the moment she trust someone she'll be the loudest person you'll ever meet. One of the girls hate the other while one of the girls admires the other. Will both girls turn into enemies or something more... romantic?

In a world where debts are paid in flesh, silence is the most valuable currency. When her father's fatal mistake brings the devastatingly powerful Yu Family to her doorstep, the quiet, introverted Kim Minjeong watches her world end in a single, bloody breath. Spared from the slaughter not out of mercy, but out of cold calculation, she is taken as living collateral by the heiress, Yu Jimin (Karina). Dragged into a glittering world of opulence and violence, Minjeong must navigate a gilded cage where one wrong word could mean death, and where her captor's chilling interest in her may be her only path to survival.

She's broke, yet she can shred. Kim Minjeong is fed up of working long hours in some run down convenience store that God knows where in Seoul, but with her luck and an audition to be a guitarist for one of Korea's biggest music agencies, SM Ent, she gets accepted. As grateful as she was, with her pay increasing massively to pay off debts, she would be unaware of the stuck up artist she would soon be assigned to work with in preparation of the idol's comeback. Ms Karina Yu, Korea's most prestigious idol. (all fictional + my work/winrina au)
