The Glass Cage Pact

In the glittering metropolis of Nanhua, a fallen industrial titan and a political dynasty's heiress enter a marriage of convenience to salvage their crumbling empires. Yet behind the flawless media facade lies a private war waged with hidden cameras, encrypted trackers, and poison. As both partners secretly plot the other's demise to escape their gilded prison, they discover that the gears of fate grind on relentlessly, indifferent to desperate pleas, where love is merely the deadliest weapon in a zero-sum game of surveillance and murder.
