"There is a beautiful woman in the north, who has left the world behind and is independent. She once looked at the city of Qingren, and then looked at the country of Qingren." It was these two women she was talking about. Although one looks innocent and cute on the outside, and the other is hot and enthusiastic, in reality, one is black on the inside and the other is black on the outside. There is no reason why the two of them have always been at odds with each other and hurt each other since they were young in the orphanage, and it will be the same when they grow up. People who were obviously far and wide seemed to be tied up by a rope, but they were assigned to the same international company again. In an accident, the two of them traveled through time. They became half-sisters, but they were different from legitimate concubines. One is the legitimate daughter loved by her father, and the other is the concubine praised by the world. The concubine originally wanted to kill her legitimate daughter and marry the prince on her behalf, but she didn't expect that the mantis was stalking the cicada and the oriole was behind her. Someone tricked her and both her legitimate daughter fell into the water. When they woke up, the temperaments of the two ladies in the Prime Minister's Mansion changed drastically, which shocked everyone in the Prime Minister's Mansion. The eldest lady is no longer the quiet woman, she has become bold and wild; the second lady is no longer the sinister and ruthless woman, she has become considerate. The changes between the two people were so great that they also refreshed the people's world view. The only thing that hasn't changed is that the eldest young lady still seems to have a soft spot for the prince, and the second young lady can't walk when seeing King Han as before, and becomes a nymphomaniac. So this is destined to be a four-corner love story. Two female protagonistsTwo male protagonists
