I recommend "Xu Fanhua's Request to Marry a Princess Consort" and "Embroidered Clothes Married". These two novels both have the female protagonist as the princess consort as the theme. The former told the story of a young lady from an official family who was obsessed with medicine and was involved in a conspiracy. After she became someone else's chess piece, she fell in love with the prince. The latter was the story of the female protagonist being forced to marry a wangye after becoming a concubine's daughter of the marquis 'fu, and gradually finding herself in the marriage. I hope you like my recommendation. Muah ~
