The Regent's Substitute Bride, the Little Physician

She actually kicked the bucket after staying up all night watching a show. How could she possibly live up to her title as a 21st-century genius of Chinese medicine now?!

What kind of ridiculous plot is this?! No matter, she doesn't care! But when she's about to fight the enemy, someone steps in front of her. “Who dares bully my wife?!” When someone looks at her a little too long, he says, “Who gave you permission to look at my wife?!”
