I recommend the novel 'Concubine is Often Pregnant: The Black-bellied Emperor's Heart's Favorite' to you! The male protagonist was the emperor of Dali Dynasty. He was very wise and powerful, but he was helpless and had a headache because of his disciple who caused trouble everywhere. The female lead had transmigrated and met this black-bellied emperor who insisted on spoiling her to the heavens! At the beginning of the novel, the male protagonist doted on the female protagonist very much, making her stay inside and not let her out. I hope you like this fairy's recommendation. Muah ~😗
