Genius Doctor: Black Belly Miss summary:

At a young age, she was a genius medical doctor who was imprisoned by her grandfather. But just as she managed to escape her shackles she met with misfortune and crossed over to another world. Now she’s the overbearing, yet good-for-nothing, eldest daughter within the Duke’s family. Everyone ridicules her for having no spirit familiar, and even her fiance takes joy in bullying her! But so what? I’ve got my accupuncture needles, so even if you’re on deaths door and begging me, I might not help you! And that man, don’t come near me! I may have saved your life, but I didn’t ask you to repay with your body!
