In a certain country in the East, Maomao, a young girl who works as a 
pharmacist in the red-light district, is kidnapped and sold to the 
imperial palace as a servant. However, she still retains her curious and 
eccentric personality and plans to work there until her years of 
servitude are over, without drawing the attention of anyone. One day, 
after hearing the rumors that the emperor's children are critically ill, 
she begins to investigate the cause, using her experience as a 
pharmacist, and successfully solves the mystery of their illness. Even 
though she intends to remain anonymous, her actions eventually catch the 
attention of an influential eunuch, and soon finds herself solving 
various mysteries in the imperial court.
