A hospital accident twenty-one years ago allowed the real daughter Su Qing to grow up tenaciously in an ordinary family, while the fake daughter Lin Xiyue became a dazzling lady of a wealthy family. When they first met, the two were sharp and pointed, tit for tat.
In the tearing of blood and upbringing, the panic of possession and loss, they glimpsed each other's fragility in the confrontation: Su Qing saw through Lin Xiyue's uneasiness under perfection, and Lin Xiyue discovered the sincerity in Su Qing's stubbornness.
After being forced to join forces by accident, they gradually realize that fate is never absolutely right or wrong, and blood is not the only criterion for family ties. Technology upstart Gu Yanchen and artist Shen Zhiyan help grow up. In the end, the two let go of their guard and went from incompatible "real and fake daughters" to best friends who understand each other best, proving that the true bond is never about blood, but in the hearts of the people.
