Unbreakable Contract

​"I didn't just lose a friend; I lost five years of a life I didn't know I had. And now? Every second of those years will be paid in blood."

​Years ago, a naive confession of love didn't just break a friendship-it ignited a war. Unable to process his own feelings, a young Jungkook chose cruelty over courage, systematically destroying Taehyung through relentless bullying until they were nothing but strangers with shared scars.

​Fast forward four years: the hierarchy has solidified. Jungkook is the cold-blooded billionaire CEO of a global empire, while Taehyung is a ghost of his former self, scrubbing floors as a janitor in the very building Jungkook owns. When their eyes meet again, it isn't nostalgia that Jungkook feels-it's a dark, suffocating need for vengeance. He traps Taehyung in an "Unbreakable Contract," a legal cage designed to humiliate him and reclaim the dominance Jungkook once held.

​But the game takes a lethal turn when a hidden truth surfaces. A forgotten, drunken night years ago wasn't just a mistake-it was the beginning of a secret life. Taehyung has been hiding a son: Brianne Kim. The discovery turns Jungkook's cold revenge into a twisted, feverish obsession. He isn't just a jilted friend or a cruel boss anymore; he is a father who believes he was robbed of his legacy. For Jungkook, this is no longer about a contract or a debt. It's a furious reclamation.

​Driven by the belief that Taehyung's silence was the ultimate betrayal, Jungkook vows to hunt down the boy who carries his blood. He will use every resource, every dark connection, and every cent of his billions to take back what is "rightfully" his.

​Taehyung must now survive a high-stakes battle of wills against a man who no longer knows the difference between love and possession. In this world of power and shadows, Jungkook will get his son and his vengeance-by hook or by crook.
