It was supposed to be pretend. Just one Christmas. One contract. One lie that would fix everything.

Struggling waitress Yoon Soo-min never expected her world to explode the moment she agreed to play fiancée to Korea's most elusive billionaire actor, Kang Jun-ho-a man whose icy gaze hides fire, secrets, and a heart scarred by betrayal. But as their fake romance unfolds under flashing cameras, snowy rooftops, and candlelit dinners, the lines between performance and passion begin to blur.

Now, with the entire nation watching, scandals brewing, and Jun-ho's past threatening to destroy everything, Soo-min has to decide: is she strong enough to survive loving a man who was never supposed to be hers?

Because what began with "Fake it"... Has him begging her to "Stay."
