In the cutthroat world of corporate Seoul, Han-joon is a man who has it all-power, wealth, and a company dynasty to inherit. But his grandfather's will comes with a shocking condition: he must be married by Christmas. Desperate to secure his legacy, he finds Seol-ah, a struggling artist with a family on the brink of financial ruin. Their agreement is simple and cold: a marriage contract for one year, a hefty sum of money, and a promise to go their separate ways.
But their meticulously planned arrangement is thrown into chaos by a single, undeniable truth: the contract didn't mention a positive test.
Now, Seol-ah is carrying Han-joon's baby-the one thing that could either be his family's salvation or his grandfather's ultimate weapon. As the fake marriage turns dangerously real, Han-joon must choose between the legacy he's been groomed for and the family he never knew he wanted. Can a cold, calculated deal become the foundation for a love that heals a broken heart? Or will their fragile new life shatter under the weight of a secret that could destroy them both?
