Can you recommend an ancient romance novel with a general as the male protagonist?

The male protagonist is a general, and the female protagonist seems to be the maid of the princess. The princess plotted for the male protagonist to marry the female protagonist. Later, the male protagonist found out that he had been set up. He ignored the fact that the female protagonist was pregnant and resolutely sent troops to war. The female protagonist fell ill from longing and after giving birth to the child, she fell ill. The male protagonist rushed back when he found out. (Non-transmigration)

Answer 1

"The Heart of the King as Bait" was an ancient romance novel. The male protagonist was an idle prince who was not put in an important position, while the female protagonist was the apple of the general's eye. The two of them had nothing to do with each other, but they became husband and wife because of the marriage granted by the emperor. However, on the wedding night, a tragedy suddenly happened. The female protagonist's family was killed, and her relatives all died unnaturally, leaving the female protagonist's eyes full of stars and turning into despair. Although it was a short story, the plot was thrilling. I hope you like this fairy's recommendation. Muah ~😗
