Wen Ting, a modern social animal, wakes up after a sudden death and turns out to be the legitimate daughter of an ancient Prime Minister's Mansion whose father died young. She has just experienced an "accidental" fall into the water. With a modern soul, she was walking around in the backyard of a deep house, but she didn't know that she had already been stared at by a pair of eyes——
Emperor Xiao Che came back from rebirth, and he wanted to protect her who died young in his previous life. He granted her favors, cleared obstacles for her, and protected her under his wings, but gradually he discovered that this "she" seemed different: she didn't understand music, chess, calligraphy, and painting, but she could say "all men are created equal"; she was not afraid of imperial power, and would frown when the young eunuch was punished; the look in her eyes when she looked at him showed no dependence from the previous life, only alienation and temptation.
One is an emperor who is guarded paranoidly with the memory of two lives, and the other is a cautious orphan girl with a soul from another world. When feudal imperial power collides with modern concepts, when his deep love encounters her secret, this redemption that begins with rebirth will eventually lead to an ending that no one expected in the midst of suspicion and love. The turmoil in the harem and the undercurrent in the court could not resist his words: "I will give you half of my world, and you will return to me."
