Mara, a wedding designer abandoned by her family, impulsively married León—an amnesiac vagrant she knew nothing about. Unknown to her, León is the missing heir of the Moreno dynasty and the very man from her one-night stand. Once he recovers, León seeks a divorce to find and marry his mystery lover—unaware Mara is already carrying his child. She accepts quietly, refusing any settlement. Forced to work as a live-in maid to repay León's hospital debts, they cross paths again. León hides his identity, while rival Selena falsely claims to be his one-night lover. Torn between duty and desire, León finds he can't let Mara go.
