In a picturesque mountain town, a blizzard of the century has left Eun-Joo, a struggling artist, and Ji-Hoon, a cold, ruthless CEO, stranded. The only available room at the cozy Mistletoe Inn is for couples only, and the discount is too good to pass up. In a moment of desperation, they pretend to be newlyweds.
But their simple lie spirals into a high-stakes deception when his family-and his beautiful, calculating ex-fianc e-show up. They're not just fighting for a discount anymore; they're fighting to protect their fragile, newfound connection from the forces that want to tear them apart.
As the snow falls, their fake romance turns into a real one, and they must decide if their love, born in a blizzard and nurtured by a lie, can survive in the real world. Can a Christmas miracle last a lifetime?
