She needed a loan. He needed a wife. The arrangement was a simple contract: one holiday, one rental, one fake marriage to secure his inheritance. Lee Jihun, a cold, ruthless CEO, thought he had it all figured out. But he didn't count on Kang Haneul, a baker with a heart as warm as her oven, who was willing to play her part for the sake of her family.

As Christmas magic weaves its way through Seoul, their fake relationship begins to feel dangerously real. One touch, one shared secret, one stolen kiss under the mistletoe blurs the lines between what's written in the contract and what's in their hearts.

The holiday ends, the contract expires, but what happens when their perfect little lie becomes the one thing they can't live without?

He's a man who has everything. She has nothing to lose. But falling for him was never part of the deal.
