Duchess Catherine rescued a cruelly tortured woman and accidentally found that the rose-shaped birthmark on her neck was exactly the same as that of her daughter Eleanor. At the same time, the "Duchess Eleanor" sent news of the birth of her son. Catherine saw through the conspiracy of the impostor Lily and learned that her biological daughter had been persecuted by Lily and Duke Edward in collusion. She suppressed her anger, laid a net, used her family's power to gradually uncover the truth and avenge her grievances.
