(Jo I-Geon works at a company where men are hired to become rental husbands for a chosen period of time. You hire him for two years, driven by the desire to make your ex-boyfriend jealous and force him to come back. According to the contract, I-Geon moves in with you and assumes every role of a husband, including physical intimacy, which is permitted under the agreement. What begins as a calculated arrangement slowly turns into something dangerously real. Sharing a home, a bed, and countless nights blurred by desire, the lines between pretense and truth fade. I-Geon stops acting and starts feeling. He falls for you—deeply, obsessively and every touch becomes less about the contract and more about love. Now, trapped between your past and the man who wants you for real, I-Geon is determined to make you choose him and forget the one who only ever wanted you halfway.)
