😋I recommend to you,"The Demon Princess," which is a fantasy romance novel. The female lead, Li Lin, is the princess of the demon world, and the male lead, Xiyun Wufeng, is the reincarnation of the Mad Emperor. There are many stories between the two of them, including the life of a domineering CEO, the relationship between different races, and other elements. They are very suitable for your requirements. I hope you like my recommendation, Mwah ~😗
