😋I recommend "Crazy Concubine for Breaking Off the Marriage: The Little Concubine's Daughter". The plot of this book is very similar to the information you provided. The female protagonist is also engaged to a prince, but for various reasons, the engagement was broken off. This novel told the story of how the female protagonist turned the tables and became the queen who looked down on everyone. The plot was compact, the writing was beautiful, and it also had the feeling of being sweet and spoiled. I hope you like this fairy's recommendation. Muah ~😗
