Winter is the best debt collector in the business. She was ruthless, efficient and completely immune to sob stories until she meets Karina, a runaway heiress who faked her own kidnapping to escape an arranged marriage... and somehow ended up owing Winter's agency a massive debt. Karina has one rule: never get caught. But when Winter finally tracks her down, she makes a last-ditch wildly reckless proposal-??

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?

Minjeong, the new basketball captain, had a smile that charmed everyone but no one really knew her. Except Jimin. Calm, untouchable, the principal's daughter who saw more than she let on. Two girls, hidden behind carefully built masks. A world that expects perfection. And a quiet pull between them that neither can forget. Not every story ends the way you hope. -WINRINA/JIMINJEONG FF-
