When the three outstanding girls and the weak sister of the Xuanhe family were choosing birthday gifts for their grandmother, they encountered a mysterious shop, fell into a weird conspiracy, and entered a strange space.
The body inexplicably returned to the appearance of ten years old, and a seemingly crazy woman told them to seek revenge on the prince who usurped the throne. In order to find their lost sisters and to protect their own livelihood, they were forced to steal from a general. Unexpectedly, they were caught and became maids in a palace. Fortunately, the four young masters in this family look quite decent.
Can they successfully take revenge? Is it really like in the plot of the novel, where the protagonist has to complete a task before he can return to his own world?
