I recommend the book " The Farmer's Wife: The Crown Prince's Favorite ". At first, the female protagonist also thought that her husband was a fool, but later she found out that he was the Crown Prince of the current dynasty. The female protagonist transmigrated into a family. Her mother-in-law was fierce, her father was a gambler, her sister was sick, and so on. She devoted herself to farming and used her medical skills to treat the people in the village. During this process, she met a man who had fainted. The two of them supported each other along the way and gradually discovered the benefits of each other. In the end, the female protagonist and her husband both received each other's sincerity and lived a happy life. I hope you like my recommendation. Muah!
