It might be referring to " His Majesty the Ninth Emperor's Escaped Wife ". The male and female leads were named Mu Yan and Mo Yan. This book was a fantasy romance novel. The male and female leads were both physically and mentally clean. There was no third party involved. There was a little abuse in the middle, and the ending was happy. The male and female leads were both very powerful. They killed Cockroach and were a strong match. When recommending a novel, one had to be careful not to mention the author. I hope you like my recommendation. Muah!
