A doctor of medicine disguised as an abandoned concubine was forced to marry a crazy prince. She saved people but he killed others, and he chased her while she was escaping.
On the night of their wedding, he went into a bloodbath in the palace but stood up for her; she vowed to divorce her husband, but he deposed the prince for her.
The throne was within easy reach, but he gave her the jade seal as a betrothal gift on the condition that she "love me again."
She supported him as regent, opened a medical clinic, took charge of the military, and became a role model for women in the world.
In the end, when the enemy attacked, he died for her overnight, and she sealed his throat with a sword, and the country and the river were safe. The two stood side by side in the court, being worshiped by all people.
