The story follows an older young woman who is jobless at home, frustrated both at work and in love, and is autistic to the point of living in her bedroom. By chance, she travels to a wealthy family in the Song Dynasty, where she is forced to get involved in internal strife in the family home. Later, she is like a palace, repeatedly in danger, and forced to rise up, create a new world, and return to herself out of the gloom.
