Real and Fake Young Master: My Queen Is an Old Enemy

Real and fake young master + changing gender + turning enemies into friends + running in both directions. In modern times, he is the real young master of the Lu family, and he is the fake young master of the Lu family. In a tampered racing car, the two died together. When he opened his eyes again, one was dressed as Emperor Ji Yun, and the other was dressed as Queen Liang Yu. Enemies become husband and wife, men become queens. He recruited concubines in the harem to form political alliances, and he used imperial skills to defeat them one by one in the previous dynasty. But when they fight to the extreme, they realize that what they really should hate was never each other.
