Jungkook is bad for everyone. Everyone except her. ​Y/N isn't your typical soft-hearted lead. She's rude, she's playful, and she's got a wall around her heart that not even a wrecking ball could crack. But as Jungkook starts trading his violence for vulnerability-only when she's watching-the line between hating him and needing him begins to blur. ​A story of what happens when a bad boy finally finds the one person worth being good for.

One cold-blooded NIA officer. One chaotic freelance hacker. One "accidental" arrest that changed everything. ​Jeon Jungkook is used to being in control. He tracks criminals, solves enigmas, and keeps his heart under lock and key. But YN? She's the code he can't crack. ​She's the vanilla perfume lingering on his skin. She's the reckless smirk that haunts his late-night shifts. She's the one person who knows that beneath the iron-pressed suit and the stoic mask, Officer Jeon is one touch away from losing his mind.

​"They don't exist. But they're the only ones who can keep me alive." YN is a brilliant, socially awkward CIA signals analyst who prefers code over conversation. When she's stationed at Outpost Zero-a classified Arctic fortress buried beneath the ice-she expects silence. Instead, she finds Bangtan Seven, an elite special ops unit so secret their names have been scrubbed from history. ​She was sent there to track enemies. She didn't expect to become the target. ​When YN cracks a "Dead Man's Switch" protocol, she discovers a terrifying truth: the very agency that sent her there has marked the unit for termination. Now, the only thing standing between her and a shallow grave in the permafrost is Jungkook, the unit's lethal point man who has traded his orders for a new mission-protecting her. ​In a place where the temperature drops to -40 degree Celsius, the only warmth Isolde finds is in the shadow of the man sworn to guard her. ​One Analyst. Seven Soldiers. A mission that was never meant to be survived.

At Preston Academy, status isn't just a luxury-it's armor. ​Y/N is a scholarship student with a simple plan: keep her head down, graduate, and escape the suffocating world of the 1%. But that plan shatters the moment she's "assigned" to tutor the school's most untouchable enigma-Jeon Jungkook. ​He's known as the Dark Prince, a cold-blooded heir who treats the world like his private chessboard. To him, Y/N is just another pawn. To her, he's a distraction she can't afford. ​But when a midnight encounter at a hidden garage reveals a secret side of the Prince-one covered in grease, ink, and raw vulnerability-the lines between tutor and student begin to blur. From illegal street races to gilded ballrooms, Y/N is pulled into a dangerous game of rebellion where the stakes are her future and his heart. ​Jungkook has twenty rules for survival in his world. But he's about to learn that the most dangerous one is the one he didn't write: Don't fall for the girl who sees the person behind the mask.

​"I have a new soulmate every Tuesday. But Jungkook is the only one who looks at me like he's tired of waiting." ​Living in a house with my older brother, Namjoon, is basically like living in a frat house-if that frat house was filled with six of the most handsome, loud, and overprotective men in Seoul. To them, I'm just the "Little Brat" who needs to finish her homework and stop falling for every boy with a nose ring and a guitar. ​I'm the girl who falls in love weekly. I'm the girl who lives for the "crush." ​But then there's Jeon Jungkook. ​He's Namjoon's best friend. He's the quiet one. The moody one. The one who fixes my laptop, remembers my favorite snacks, and never joins in when the others tease me about my latest heartbreak. ​While I'm looking at the rest of the world, Jungkook is looking at me. ​Behind closed doors and under the noses of six "big brothers," the rules are starting to break. The stares are lasting too long, the "tutoring" is getting too heated, and the line between "family friend" and "forbidden lover" is about to be crossed. ​In a house full of lions, the deadliest one is the one I was never supposed to touch.

Rule #1: Never let Jeon Jungkook win. ​Rule #2: Ignore the way he looks in a white t-shirt. Rule #3: Don't fall for the jerk who makes it his life's mission to annoy you. ​Y/N is very good at following the rules. Jungkook is very good at breaking them. A story of two rivals, one shared project, and a one-sided love that's been hidden behind sarcasm for three years.

​Jeon Jungkook is a ghost. A highly-trained, tactical specialist who lives by a strict set of protocols, thrives in silence, and prefers the company of his custom sidearm to actual people. He was expecting his new assignment to be a standard protection detail: high-stakes, high-security, and high-intensity. ​He wasn't expecting Y/N. ​The daughter of the country's most dangerous whistleblower is a walking, talking breach of protocol. Y/N doesn't do "low profile." She does sequins, 2 AM diner runs, and a pink, glittery suitcase that Jungkook is forced to haul through safe houses like a glorified bellhop. ​To Jungkook, she's a "Target Attraction Hazard." To Y/N, he's just a grumpy, tatted wall of muscle who needs to learn how to have a good time. ​While Jungkook scans every room for exits, Y/N scans every room for the best lighting. While he talks in radio codes, she talks in sarcasm. It's a war of wills where his "professional" armor is being chipped away by her unhinged chaos-and her "I don't need help" attitude is being softened by the way he looks in a tactical vest. ​In a world where the guns are real and the stakes are life or death, the biggest threat might just be the one thing Jungkook didn't plan for: falling for the girl he's supposed to be watching.

"They called him the General of Ash-a monster whose heart was as frozen as the obsidian peaks he ruled. I was the Kkon-bi, a princess sent not to be his bride, but his sacrifice. ​In the Black Fortress, love is a death sentence and mercy is a myth. But when the 'True Yearning' awakens, a cursed soul-bond that bleeds violet light and shared pain, the lines between captor and savior begin to blur. To save my people, I was supposed to kill him. Instead, I taught a monster how to bleed. ​Now, as the South marches for war and the North thaws with a passion that threatens to burn us both, I have to decide: will I be the bridge that saves the world, or the match that sets it on fire?"

​"I was trained to be a weapon, but she's the only one who ever made me feel human. Now, I'll burn the whole world down just to keep a smudge of flour on her nose." ​ Y/N Park is the "Soft Liability" of the Seoul Syndicate-the Chairman's daughter who brings banana bread to a den of killers and trips over her own shadow. Jeon Jungkook is "The Raven," the syndicate's most lethal, cold-blooded asset, tasked with one job: protect the girl who doesn't belong in his world. ​What starts as a forced proximity "bodyguard" assignment spirals into a high-stakes game of obsession and betrayal. From the neon-lit gambling dens of Busan to a secluded cabin on the edge of the world, Jungkook must decide if he's a tool of the Syndicate or the protector of the only girl who ever saw the man behind the ghost. ​In a world where kindness is a weakness, Y/N is his greatest vulnerability-and his only reason to survive.

She walked away five years ago after overhearing the one thing she was never meant to hear. Now she's back-bound by a contract she can't break, working for the man who never forgot her. doesn't believe in love. Only control. Only power. Only terms that can't be negotiated. And her? She was supposed to be nothing more. But the way he watches her says otherwise. In a world where everything has a price, the most dangerous thing isn't the contract- ...it's the feelings they never finished.
