Yu Karina is a wealthy, independent woman - driven by a single obsession: avenging her sister. A suicide? She never believed it. Alongside her brother Kai, she investigates, digs through silence and lies, until an undeniable truth emerges: the agency where her sister worked pushed her to take her own life. Soon, one name rises above all others, heavy and threatening: Kim Duho, the agency's CEO. From that moment on, the path is set. The Yu siblings are ready for anything. Even to kill. But nothing will go according to plan. Too many variables slip beyond their control. Too many unstable elements begin to fracture a meticulously crafted revenge. And among them, one presence changes everything: Kim Winter. She embodies everything the Yu family despises - the cold, blood, winter, snow. And yet, she now stands at the very center of their fate. Because revenge is never an isolated act. It consumes, it distorts, and it never spares those who dare to begin it.

Jimin Yu has everything: wealth, flawless appearances, glittering nights, and a life polished like a gilded portrait. But behind the marble walls, her family is nothing but ruins-coldness, pressure, secrets, and an inheritance that weighs heavier than a prison. Minjeong Kim lives the exact opposite: a simple life, too simple, almost suffocating. Between school, part-time jobs, and a past that refuses to heal, she doesn't have the luxury to dream... let alone waste time on a girl like Jimin. They should never have crossed paths. They should never have liked each other. And yet. When a declined invitation, a forgotten coffee, and a few misunderstood words make them collide head-on, everything spirals: resentment, attraction, clumsy mistakes, misunderstandings... and that dangerous urge to move toward the other despite everything. As their families crumble, as mysterious figures rise from the shadows, and as the truths they tried to outrun crash back into them, Jimin and Minjeong are left with no choice: face the world, or face themselves. Love, secrets, betrayal, and invisible wounds. Two girls who have nothing in common. Two destinies that intertwine when everything should tear them apart. And what if their encounter was only the beginning of a much darker story than they ever imagined?

a short story about winter impulsively asking her roommate karina to pretend to be her wife for a weekend family gathering.

Kim Minjeong (Winter) just wanted to study, stay unnoticed, and survive her first day of school at Ae University. She didn't expect to catch the eye of Yu Jimin (Karina)-- the campus' untouchable queen. What begins as glances across the hallway turns into a slow, consuming obsession. And when Karina wants something, she doesn't ask. She takes. But someone-no, someTHING starts walking on Ae University's hallways.

sunlightwrites | 2025 Karina Yu is a university senior who has turned flirting into a high art. Confident, charming, and impossibly smooth, she lives for the thrill of the chase-not for romance, but for the fun of seeing how easily she can make people blush. Her latest, and most intriguing, target? Winter Kim, a brilliant, no-nonsense freshman physics major who takes everything in life with deadly seriousness. For Winter, the world is a series of problems to be solved logically, and she has no time for the uncalculated chaos of human interaction. ​When Karina is assigned as Winter's student buddy, she sees it as the ultimate challenge. Armed with a devastating smile and a playbook of hilariously over-the-top schemes, Karina launches "Operation: Fluster the Nerd," a relentless campaign of calculated collisions, witty one-liners, and shameless compliments designed to crack Winter's stoic exterior. ​But as Karina's playful pursuit continues, the lines begin to blur. Winter, despite her best efforts to remain immune, finds her carefully organized world turned upside down by Karina's vibrant and chaotic energy. And Karina, who only ever flirted for sport, starts to realize that the genuine, adorable reactions she gets from Winter might be something she wants to keep. "FLIRT" is a fluffy, comedic story about opposites attracting, where a girl who lives for the game discovers the one person who makes her want to stop playing.

Winter shows up to meet her bias. Karina shows up to work. But one unexpected moment of eye contact sends both into emotional chaos. After the event, Karina refuses to let the mystery girl slip away and asks her staff for Winter's contact-breaking every rule she's known.

They were told to focus only on debut. On perfection, on fame, on shining brighter than anyone else. But in the shadows of the practice room, something else grew- a secret Winter couldn't hide, and a feeling Karina wasn't supposed to return. Between jealousy, forbidden closeness, and the world watching their every move, one question remains: how far can love survive under the spotlight?

Karina doesn't date athletes. Especially not cocky ones. Winter's reputation as the school's golden girl-and the way she openly teases Karina in front of everyone-should make her the last person on earth Karina would fall for. But late-night practices, stolen glances, and one too many bets might push the cheer captain into dangerous territory: catching feelings.

When rising K-pop soloist idol Winter gets caught in a dating scandal with her K-pop idol friend jeno, her team hires Karina - a random stylist assistant - to pretend to be her girlfriend to "control the narrative." They can't stand each other at first, but pretending to be in love on camera feels... alarmingly real off camera too. Now fans are shipping them, the media's obsessed, and Winter might actually be catching feelings she shouldn't.

Moving in with three roommates was supposed to be fun. It wasn't. Karina swears she only wanted peace, quiet, and an organized closet. What she got instead: • A chaos gremlin named Ningning who eats her leftovers. • A "peacekeeper" Giselle who's somehow always late to peacekeeping. • And Winter - the most annoying, sarcastic, loud, messy, frustrating roommate ever... who also happens to look way too good in sweatpants at 3 a.m. Oh, and let's not forget the neighbors. ITZY lives right across the hall, and they've basically declared war. Between prank battles, rooftop arguments, and accidentally romantic moments, Karina's about to learn that love doesn't always knock politely. Sometimes, it barges into your apartment and eats the last bag of chips.
