This is an ancient romance novel. The protagonist disguised as a man to save the life of the prince, but unexpectedly met with pregnancy. In the end, she fell in love with the prince and guarded the country together. There were no palace fights, sadomasochistic love, mistresses, and no extreme relatives in this novel. It was very suitable for readers who liked the ancient language but could not accept too many complicated plots. I hope you like my recommendation.
