Was there an ancient romance novel where the male protagonist was the emperor and the female protagonist was much older than the male protagonist? After the male protagonist grew up, the female protagonist became his necessity and was always doted on by him?

I recommend "I'd rather be a favored concubine than a queen." The male protagonist of this ancient romance and classical fictional novel is the emperor. The female protagonist has just entered the palace and is only a small talent with a low status. However, she is favored by the emperor. It's not that she is favored alone, but she is constantly favored. However, in the harem, a tall tree attracted the wind. The female lead was frightened at every step, and her gentleness and virtue were repeatedly questioned. This was a harem novel. It was impossible for the male protagonist to only have the female protagonist. Those who like my favorite novels can take a look. I hope you like this fairy's recommendation. Muah ~😗
