In the glittering, cutthroat world of Seoul, Lee Haneul, a struggling Christmas ornament artist, has one impossible deadline: she must marry by Christmas Eve or lose her grandfather's legacy to a scheming relative. Her last hope? A fake marriage to Kwon Taehyun, a cold, ruthless CEO who shattered her heart seven years ago.
Their contract is simple: a month-long charade of a whirlwind romance to secure her inheritance. But as fake dates, public kisses, and late-night confessions blur the line between a business deal and a second chance, Haneul discovers the truth behind Taehyun's betrayal is far more complex and heartbreaking than she ever imagined. As their carefully constructed lie spirals into a dangerous mix of corporate espionage, family secrets, and emotional turmoil, they must confront the ghosts of their past.
With a powerful enemy threatening to expose their every secret and a deadline looming with the first snowfall, Haneul and Taehyun are in a race against time. Can their love story become real before the truth-and the snow-melts it all away?
