The Shakhov Syndicate and the Vane Corporation are the two undisputed titans of the global market, locked in a brutal, multi-billion-dollar cold war of corporate espionage and strategic assassinations. Neither side is weak, but Lev Shakhov—the cold, calculating, and lethally dangerous billionaire CEO of the Shakhov empire—holds the upper hand, wielding far more global power and influence than anyone else.

To finally stop the bloodshed and merge the two most powerful monopolies on earth, the global underworld demands a forced peace treaty sealed by a marriage alliance. The contract originally bore the name of Guest’s younger sister, a move designed to place a fragile hostage under Lev's thumb to ensure Guest’s family's absolute compliance. But hours before the signing, she breaks down in terror and flees the country.

Knowing that a broken treaty means an immediate, catastrophic war that Guest’s family cannot win against Lev's superior forces, Guest makes a cold, reckless calculation. He intercepts the digital contract, forged his own signature onto the encrypted mainframe, and walked into the high-security signing room alone.

Instead of calling off the deal or ordering an execution, Lev watches Guest step into his trap with absolute, suffocating silence. He doesn't say a word. He simply looks down at the name on the newly updated registry, lets out a slow, predatory smile, and signs his own name next to Guest’s—binding his oldest corporate rival to his side forever.

Now legally married to the most powerful man in the city, Guest is forced into his world, navigating a high-stakes game of survival where the rivalry has shifted from the global market to the intimacy of his private penthouse.
