Jazmin woke up with a splitting headache and red system error codes flickering across her vision, only to realize she was trapped in a bizarre reality as a billionaire's contract wife. Before she could even process the alien data in her mind, her arrogant husband, Adrian, threw a harsh divorce agreement onto her lap. "You get nothing. Melody is the one I love. You were just a placeholder," he sneered, demanding she leave the marriage without a single cent. When she didn't break down in tears, he grew furious and lunged forward, his fingers closing tightly around her throat to remind her of her place. His wealthy family expected her to quietly accept her public humiliation, while her greedy adoptive parents immediately demanded a payout, treating her like a worthless ATM. They all thought she was still the same fragile, pathetic woman who would beg for their scraps and cry over their cruelty. They had no idea that the original Jazmin was already dead, and the system had loaded a completely different, indestructible entity into her body. Jazmin didn't shed a single tear or gasp for air. She simply grabbed Adrian's wrist, shattered his bones with a sickening crunch, and tossed him through a glass window like a bag of trash. "I'd rather dance alone in hell than be a dog in your heaven." Taking the massive settlement she extorted, she walked straight into the arms of his deadliest rival, ready to tear this entire world apart.

I died in the apocalypse, only to wake up as Kenzie Banks, a bankrupt high-society monster in an interstellar beast-world. But before I could even process my new reality, a cold AI voice informed me of my impending death. "Your contract beast-husbands possess the legal right to execute you at the end of the two-month trial period." I rushed to the basement and saw the horrific truth. The original Kenzie had starved them, whipped them with thermal blades, sent their brothers to die as cannon fodder, and framed the youngest to rot in a maximum-security prison. Now, these lethal, broken men were methodically planning to rip my organs out the second the contract dissolved. To make matters worse, she had squandered her fortune on a man who despised her, leaving me two million credits in debt and facing imminent exile to the deadly wastelands. I had survived rotting zombies on Earth, only to be trapped in a weak, universally hated body, doomed to be butchered by the very people I was supposed to call family. Why did I have to pay the ultimate price for a psychotic woman's deadly sins? I refused to just sit around and wait for my execution. Tapping into my apocalyptic subspace inventory, I hauled out military-grade rations, healed their bleeding wounds, and slammed a legally binding divorce contract on the table. If I wanted to survive this sixty-day countdown, I had to turn my executioners into my loyal allies—starting with breaking the husband she framed out of prison.

For seven years, I hid my MIT Ph.D. and my identity as a top haute couture designer to be the perfect, obedient wife to billionaire Cornelius Lambert. But on our anniversary, while I waited at home with a cold dinner, I found him at a Michelin restaurant with his childhood sweetheart, Halle. My seven-year-old son sat between them, laughing loudly. "Mom is too boring. I wish Aunt Halle was my real mom." Cornelius didn't defend me. He just smiled and affectionately ruffled the boy's hair. When I finally packed my bags and left, I accidentally triggered an old AI robot prototype Cornelius had given me years ago. A hidden recording played his voice from the very night he proposed. "Why marry her? Because she's easy to control. Halle doesn't want to settle down yet, so Cassidy is just a perfect, temporary shield."

Dragged back to his primitive camp, her nightmare only escalated. When she used her modern first-aid kit to save a dying hunter whose stomach had been ripped open, the tribe didn't thank her. Instead, a jealous tribeswoman named Greta and a ruthless Shaman incited a violent, torch-wielding mob. "Burn the witch before we all die!" They marched on the Chief's cave, demanding Eleanor be burned alive, claiming her life-saving stitches and antibiotics were dark magic that would curse them all. Eleanor was terrified and furious. She had just pulled a man back from the brink of death using basic medical science, yet she was about to be slaughtered by a mindless mob simply because they couldn't understand her language. Was she really going to be burned at the stake for an act of pure salvation? But when the hunter's fever broke and he walked out alive, the angry mob dropped to their knees in absolute reverence.

A colossal black wolf dropped from the canopy and crushed the beast's neck to save her. But before she could even breathe, the wolf transformed into a towering, naked primitive man with glowing gold eyes. He hauled her back to his savage tribe, where she was instantly treated like garbage. The women sneered at her fragile human body, and the men eyed her like fresh meat. The tribe leader's jealous daughter even handed her a waterskin laced with a terrifying alien breeding drug, hoping to turn Cora into a mindless spectacle of lust in front of the entire settlement. "Drink. You look like you're dying," the daughter sneered, waiting for Cora to lose her mind. Cora was terrified and completely out of her depth. She didn't understand why this lethal Alpha warrior looked at her with such dark, consuming possessiveness, or why he was willing to slaughter his own people just to protect her.

Julia confined him to a cramped guest room, warning him to stay out of her life. To make matters worse, his other estranged fiancée, an elite military commander, barged into the penthouse just to throw an annulment in his face. "You are a pathetic, bottom-feeding parasite!
