Qingzhi, the Female Physician

Qing Zhi only wants to be a neatly dressed doctor practicing medicine in ancient times. So why is it so hard to maintain her image after meeting a certain someone? Her unconventional life as a doctor begins...

Plain-language synopsis:

Qing Zhi, who disguises herself as a man to practice medicine in her father's place, never expected trouble after treating Lu Shikang, the biggest playboy in Jiangbei, and having him discover that she was a woman.

Lu: My best buddy is gone. You turned him into a woman, so you owe me another one.

Qing Zhi: How am I supposed to do that?

Lu: Marry me.

Qing Zhi: I'd rather die.

Lu: If you can't make it up to me, then keep disguising yourself as a man and being my buddy. My buddy and I eat, live, and sleep together. We can keep doing that until the end of time...

Qing Zhi: Who wants to spend eternity with a wastrel like you...
