When an overworked architect, Eun-ji, agrees to a fake marriage with a charming CEO, Lee Jin-woo, to escape her family's judgmental Christmas dinner, she has no idea what she's signing up for.
The contract is simple: pretend to be in love for one week, secure a business deal, and go their separate ways. But as their carefully constructed lie begins to unravel, Eun-woo finds herself falling for the man she's only pretending to love. When their fake relationship becomes a public sensation, they must decide if their love is a carefully choreographed performance or a beautiful, undeniable truth.
