I can recommend "Trash Defies the Heavens: The Strongest Princess Consort" to you. The female protagonist of this book transmigrated to become the useless miss of the general's residence. She was originally engaged to the Crown Prince, but after the Crown Prince regretted his marriage, the female protagonist entered the eyes of the Prince, and the relationship between the two began. I hope you like this fairy's recommendation. Muah ~😗
