Shen Zhiyi, a bride-to-be, finds out she is unexpectedly pregnant due to a bizarre medical mix-up. When she subsequently discovers her fiancé's infidelity, she calls off the wedding immediately and decides to raise the child alone as a single mother. Two years later, Gu Chenzhou—the cold, powerful president of the prominent Gu Group—presents her with a DNA test proving he is the biological father of her child.
To give their son a complete family, Gu Chenzhou proposes a "trial marriage" contract with strict terms, promising a temporary arrangement with no romantic obligations. Despite his initially aloof demeanor, Gu Chenzhou becomes fiercely protective and devoted to both Shen Zhiyi and their child. What began as a businesslike arrangement transforms into real affection as Shen Zhiyi realizes Mr. Gu fell in love with her long before the "trial" ever began.
