{Also known as From Empress to Lone Phoenix, Still Unfazed} [A bittersweet setup] [The male lead is faithful before he meets the female lead and remains faithful after they get together. Once cracks appear in their relationship, he no longer deserves to keep her. Whether he stays faithful after that is beside the point.] [An unconventional run-away-with-the-baby plot + no forgiveness!!!]
Wan Zhenxi, a college student born after 2000, transmigrates to the fictional Ming Dynasty and becomes the three-year-old legitimate daughter of a grand secretary.
She and Yu Yanzhi, the legitimate second son of the Vice Minister of War, grow up as childhood sweethearts. At a palace banquet, she meets Zhu Xianjun, the former crown prince who has been demoted to Prince Yi, and casually helps him deal with a cruel servant who is giving him trouble. From then on, an inexplicable bond forms between them.
The three grow up together through many ups and downs. Zhu Xianjun understands Wan Zhenxi's special nature and her attitude toward love inside and out. During the years he spends fighting for the throne, he comes to understand his feelings for her. He promises that she will be the only one for him for his entire life, and eventually Wan Zhenxi agrees to marry him.
Drawing on her own knowledge, Wan Zhenxi helps Zhu Xianjun, a broad-minded man with far-reaching vision, win the support of the court officials.
Yet Heaven loves playing tricks. After many years as emperor and empress, they still have no children. Zhu Xianjun breaks his promise, taking concubines and fathering a child. By then, Wan Zhenxi has already left him, carrying a child he knows nothing about. From then on, the world is wide and the road is long: he is free to go wherever he pleases.
