The heroine is a princess who lost her country. After her country was destroyed and her family was destroyed, she took the role of the foolish legitimate daughter of the enemy's general and entered the palace as the queen. The emperor favored her because he used her as a tool to humiliate the previous dynasty; the ministers respected her because they were afraid of the military power of her "natal family". She plays the role of a charming and brainless stunning beauty every day, but in fact she is secretly planning to take advantage of the contradictions between various forces to find opportunities for the restoration of the country and revenge.
