He was looking for novels like " Your Highness, I Want to Divorce My Husband ", in which the female protagonist transmigrated and became the concubine of the emperor or the crown prince.

The book 'Godly Doctor's Cute Concubine: The Silly Prince is Black-bellied' fits the description of the problem. I recommend it to you. The female protagonist was a divine doctor. After removing the voodoo poison from the male protagonist's brother, the female protagonist followed the male protagonist home to be a guest. The male protagonist was a black-bellied prince. He was somewhat paranoid and controlling, but he also doted on the female protagonist very much. If you like ancient romance and intriguing relationships, you can consider reading this novel. I hope you like this recommendation. Muah ~

😋I recommend the following two books to you: 1. The female lead was the uncrowned king of the assassin world, and in one day, she transmigrated to become the useless crown prince of the empire. It matched the title. The female lead was the crown prince consort! The male lead was the emperor who was not pleasing to the eye. The two of them were in love/hate until the end of time. 2. "Defiant Queen: The Emperor Flipping Over": The female protagonist was spoiled into a fairy in her previous life. In this life, she has an aura that can obliterate everything. She has become the most mysterious young master of the Demon Palace. The male protagonist is one of her pursuers. There is a strong attraction between them and the emotional entanglement of love and hate. Moreover, the male protagonist is also an "emperor", which fits your requirements very well.

I recommend I Was a Wolf: A Queen in Sheep's Clothing to you.

In addition, this novel also had many elements such as time travel, palace struggles, emotional entanglements, and so on. It was worth reading. I hope you like this fairy's recommendation. Muah ~😗

I recommend 'After We Divorced, I Was Spoiled by the Crown Prince'. Qin Zhao, the female protagonist, traveled to ancient times and was doted on because she took care of the crown prince, Xiao Ce.

The male protagonist, Xiao Ce, had always doted on the female protagonist, which was intoxicating. I hope you like my recommendation.😗

The recommended novel was " A Lifetime of Domination: The Heart-stopping Crown Princess." The plot of the novel matched the description of the problem. The protagonist girl became the crown prince's consort and helped the crown prince solve his problems. However, the crown prince had a secondary consort. Rumors said that he doted on her, but in fact, he only allowed his subordinates to consummate their marriage with the secondary consort. It was only when the concubine was captured that the guard told the truth. Interested readers can give it a try. I hope you like my recommendation.
