A "War King" who controls global arms trafficking and whose true face has never been seen, agrees to a contractual marriage proposal from a mysterious woman at a masquerade ball to marry for true love instead of money. He disguises himself as a low-level salesman and marries into a wealthy family. By day, he's trampled by colleagues at the company; by night, he's treated as worthless by his mother-in-law. Yet he secretly saves his wife's failing company time and again—only to have his rival take all the credit. When his wife is kidnapped, he discovers that the Hart family's decline was orchestrated by this rival all along. At the engagement banquet, he reveals his true identity, settles accounts item by item, and reduces the villain to nothing overnight.
