In the high-stakes world of corporate Seoul, ruthless CEO Lee Ji-ho is on the verge of a career-defining merger when a sudden blizzard traps him at a remote mountain inn. His only chance to salvage the deal? A marriage pact with the last person he expects to see: a fiercely ambitious journalist, Han Seo-yeon, who is secretly on the run from a career-ending scandal of her own.

Forced to pose as a happily married couple to secure the last available suite, their lives become a beautiful, dangerous lie. But as the lines between their deception and their feelings begin to blur, they discover a shocking truth: their separate missions are intertwined, and their fake marriage has led them to the very man who orchestrated both of their downfalls.

Trapped in a web of corporate espionage and political corruption, Ji-ho and Seo-yeon must decide if their fragile alliance can survive the truth-and if the love they found in a snowstorm is powerful enough to save them both.
