Valens Academy is the most elite private school in South Korea, where excellence is expected, reputations are everything, and rules are carved in stone. Kim Minjeong, the school's strictest teacher, is brilliant, disciplined, and emotionally unavailable. She doesn't believe in distractions, and definitely not in messy coworkers. Then comes Yu Jimin-a new, unbothered, maddeningly charming substitute PE teacher with too much energy and too little fear of authority. They were never meant to cross wires. But every reaction needs a catalyst. Unpublished on accident. Started on: 07/06/25

Winter Kim has always kept to herself-quiet, distant, and seemingly powerless in a university where everyone is expected to shine. But when strange dreams begin to haunt her and a forgotten god stirs beneath the surface, the truth about who she is starts to unravel. As the danger draws near, secrets are forced into the light, and Winter finds herself at the center of something far greater than she ever imagined. Mysterious powers. Forbidden bonds. A god that refuses to be forgotten. And buried beneath her silence is something dangerous waiting to rise.

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.

Winter Kim spent years idolizing Karina, believing that following in her footsteps would bring them closer. She transferred schools, joined Kwangya Entertainment, and stepped into Karina's world hoping to stand beside her. But admiration is a dangerous thing. To Karina, Winter wasn't a fan, she was a threat. She hated the way Winter followed her, how their mentors praised her, how she was suddenly everywhere. Yet no matter how much Karina tried to push her away, she couldn't ignore her. And as rivalry turns into tension, they begin to wonder, is it really hate, or something more?

The Yu family built an empire on power, wealth, and perfectly calculated deals. Yu Karina is no exception-sharp, relentless, and always in control. To secure their inheritance, all she needs is one final piece to fall into place: Kim Duho's firstborn daughter agreeing to marry her brother. Winter, the ever-elusive heiress, is anything but easy to persuade. She sees through Karina's every move, meets her sharp wit with an even sharper tongue, and makes it painfully clear-she has no interest in being part of the Yu family's schemes. But Karina doesn't accept losses. She negotiates. Manipulates. Wins. And Winter is just another deal waiting to be closed. At least, that's what she tells herself. As secrets surface and time runs out, Karina finds herself caught in a dangerous game-one where the lines between manipulation and genuine desire begin to blur, and falling for Winter might cost her more than she's willing to give.
