The heroine Su Qingyuan, heir to a family of modern Chinese medicine, accidentally transformed into the most unpopular concubine in the Jing'an Marquis Mansion. The original owner was timid and cowardly. Because her aunt Su Qingyao refused to marry Xiao Jue, the mad and cruel prince who was rumored to be a wife-suppressing and cruel man, she was forced out by her aunt to marry her instead.
The male protagonist Xiao Jue, the seventh prince of the current dynasty, King Feng Rui, is rumored to have a disfigured face, a crazy temperament, and the death of three fiancées. Everyone in the capital avoids him. In fact, not only does he have a peerless appearance, but he is also a ruthless person who secretly controls half of the court. He has been looking for someone for many years - the "Little Yuan'er" who saved his life when he was hunted and killed when he was young. It is the white moonlight engraved in his bones and blood.
The heroine thought that she was a substitute cannon fodder who could be killed by the crazy criticizing prince at any time. She was careful and careful throughout the whole process, but she didn't know that she was the Bai Yueguang who the prince had been looking for for ten years. Everyone thought she would end sooner or later, but she ended up being doted on by the prince.
