To save her critically ill younger brother, Leah is forced to sign a one-year contract marriage with Locke, a cold and aloof CEO, playing his wife in name only in exchange for the surgery fees. Starting as strangers who set the ground rule of "no falling in love," the two gradually grow closer while living together. Moved by Leah's resilience and kindness, Locke quietly resolves her troubles, protects her family, and defends her in public time and again; Leah, in turn, lets down her guard and falls for this man with a cold exterior and a warm heart. After the truth of their contract is exposed by a romantic rival, Locke does not hesitate to confront his family and abandon business partnerships to publicly stand by Leah. In the end, he tears up the contract and proposes with his true feelings—what began as a contractual marriage becomes a genuine love, culminating in a grand wedding.
