To save her critically ill brother, Leah signs a one-year contract marriage with the aloof CEO Locke in exchange for surgery fees. They agree "no falling in love," but living together gradually changes everything—Locke quietly protects her and defends her in public, while Leah lets her guard down and falls for him. When a rival exposes the contract's truth, Locke defies his own family to stand by her, ultimately tearing up the agreement and proposing with his heart. What began as a contract marriage becomes true love, culminating in a grand wedding.
