Both stories revolve around a woman who pretends to be someone else, entering a powerful family with hidden secrets and dangers. The male leads start cold and suspicious but slowly fall deeply in love, creating strong chemistry and emotional scenes.

Both dramas feature identity deception, chaebol families, and a contract relationship turning into real love. Mask is darker and more melodramatic, while Bride of the Century adds a supernatural twist with a family curse, but the emotional core and slow-burn romance feel very similar.

In both Mask and Bride of the Century, the female leads are ordinary women who step into someone else’s life and face danger, secrets, and betrayal. Watching them navigate lies and find true love is satisfying and emotional. Both shows keep you hooked with plot twists and character development.

They are adapted from novels by the same author 'Wei Yu'.
Both contain Mystery, Adventure and Fantasy elements with group working together to solve a mystery.
