Elena is drugged by her stepfather and, at a masked ball, has a night with Vincent—a powerful heir who can't touch any woman due to childhood trauma. She gives birth to Leo, but Frank sends the baby to an orphanage. Vincent recognizes his tie at the scene, adopts Leo, and brings him home.
Desperate to reclaim her child, Elena applies as a wet nurse at Cunningham Manor, reuniting with Vincent—neither recognizes the other. Leo only drinks Elena's milk. Vincent discovers Elena is the only woman he can touch without repulsion, and gradually falls for her.
Frank's schemes and Lina's sabotage are repeatedly thwarted by Vincent. Elena learns her child has been "adopted" by the Clintons, but discovers the child isn't hers—the orphanage director was deceiving her. Vincent produces the tie: Leo is her son, and Vincent is the masked man from that night.
Vincent confronts his father Charles, exposing the abuse that drove his mother to suicide. Charles concedes, accepting Elena. The family of three reunites in a grand wedding.
