Han Ji Eun (Song Hye Kyo), an aspiring scriptwriter, finds herself in a whirlwind when her supposed friends deceive her into believing she’s won a vacation, only to sell her cherished childhood home, ‘Full House’, in her absence. On her journey, she meets Lee Young Jae (Rain), a renowned actor, and their initial encounter sets off a series of comedic mishaps. Upon returning, Ji Eun is stunned to discover that Young Jae is now the owner of her beloved house. Despite their clashing personalities – he’s fastidious and easily irritable, she’s carefree and messy – they reluctantly agree to cohabit. Initially, Ji Eun works as his maid to save money for her home’s repurchase. Their arrangement takes a dramatic turn when Young Jae, seeking to win back his ex-lover, proposes a contract marriage to make her jealous. However, as their charade deepens, unexpected emotions emerge, complicating their once-straightforward agreement.
