Were there any good Korean dramas that had a PE teacher as the main character and also covered the storyline of family relationships?

In this ancient romance novel, the female protagonist, Su Qingqing, was a young medical doctor who was said to be a maid of the chief assistant's family. She seemed to be bullied by others, but in fact, she was treating the wronged people behind their backs. Among them, the brother-in-law of the chief assistant's family, Lin Runqian, is a physical education teacher. Although the character setting is a little different, I believe you will also like the story of this sweet favorite novel. I hope you like my recommendation. Muah ~
