I recommend "The Evil Prince's Busy Wife" to you. The male protagonist in the book has heaven-defying medical skills and amazing martial arts. He changes his face and identity. From male to female, he is a peerless handsome man. The female lead was a modern gold medal killer. After being caught in bed by the scumbag, she fought back the white lotus without hesitation and divorced the scumbag. In the story, the male protagonist always silently protected the female protagonist, and in the end, he won the beauty. The two of them loved each other until their hair turned white. I hope you like this fairy's recommendation. Muah ~π
