Answer 1

The female lead is married to a servant girl named Dark Fragrance, and the female lead's sister is the Crown Princess.

This plot was more common in novels or television dramas. The female protagonist was usually arranged to be the substitute bride of the prince while Dark Fragrance was the female protagonist's maid. The female protagonist's sister was usually the Crown Princess. There might be some complicated relationships between the two of them. This kind of plot usually brought some plot challenges because the identity of the female lead and the sister were more complicated and required the author to make clever arrangements and explanations.
