Are there any romance novels that have the male protagonist as a submissive or a fool, and don't require the protagonist to act dumb?

I recommend the ancient romance novel "The Princess Consort Is Enchanting, The Prince Bows Down" to you. The male lead was a fool, and he was not pretending to be stupid. He even had a little tail. The story was very interesting, full of fantasy and romantic elements. It was worth watching. I hope you like this fairy's recommendation. Muah ~😗
