A modern surgeon Chloe Sullivan undergoes transmigration and becomes a foolish rural girl in ancient times, who is sold to hunter Finn Grant, who bears a wrongful murder charge. She feigns madness to protect herself, secretly uses her medical skills to detoxify and heal his wounds, and clear his name. She rises from living in a pigsty to become a first-rank official lady, while the cold-faced hunter regains his identity as a war god. The two join hands to compose a legend of mutual affection and support between two powerful partners.
