It Was Only Three Years After He Ascended the Throne That the Regent Discovered That I Was a Woman.

Female protagonist's perspective: Song Jingchen was originally an unpopular prince who disguised himself as a man and relied on poisonous potions to maintain his manhood. I originally wanted to wait until one of my imperial brothers came to the throne, and I would fake my death and go out of the palace. What I never expected was that the imperial brother was me, and Song Jingchen took the throne by himself... How could I go about this? Male protagonist's perspective: As the regent, Chu Henglin originally wanted to help the ailing emperor secure his position, and then he would become famous by helping the emperor choose a queen who could be a mother to the world. But what I didn't expect was that the little emperor's illness never got better, and later he even became more and more frail. Why, he started to look more and more like a girl?
