Choi Ji-eun is drowning in debt, her dreams of being an artist shattered. So when a ruthless, devastatingly handsome CEO, Kang Ji-hoon, offers her a lifeline-a fake marriage for three months in exchange for a fortune-she takes it. It's a simple contract, a business transaction. Or so she thinks.
But when she steps into his world, a gilded cage of power, deception, and family secrets, the lines begin to blur. He's a man of icy control, yet his touch sends shivers down her spine. He's her fake husband, but the way he looks at her feels terrifyingly real. As a Christmas deadline looms and an explosive secret from her father's past threatens to unravel their lives, Ji-eun finds herself in a dangerous game where the stakes are higher than money. She's a ghost in his life, a pawn in his game, but the deeper she falls, the more she realizes this isn't a game at all. It's a war. And the only thing she's fighting for is his heart.
