Evelyn, heir to the Vance Group, faces imminent asset liquidation. To save her family business, she strikes a marriage-and-merger contract with Arthur, the rightful heir of the Blackwood lineage who has been lying low under an assumed identity. Together, they fend off betrayal from legal counsel Chloe and the capital siege launched by ruthless rival Julian. Traveling across multiple locations, they crack data traps and uncover long-buried truths: Arthur’s uncle staged an arson to seize power, and Evelyn’s father faked his own death. This transactional marriage born out of mutual interest blossoms into deep affection as they shield each other through life-and-death crises. After shattering all conspiracies, they lay down their commercial power, escape the chessboard of capital, and stay together to embrace a quiet, peaceful new life.
