The Apothecary Diaries Manga, Vol. 1

Maomao tries to keep her head down as a servant in the inner court (the emperor's booty call compound) but her education level soon becomes apparent. Her knowledge is medicine and poison is the solution to some situations but superior reasoning skills are the solution annoyingly often. I would rather the focus stay on her specialized skill set.

A hot feminine guy (assumed eunuch but suspiciously not confirmed) acts as puppet master of the inner court. He keeps flirting with Maomao and she has no interest.

Art is pretty but the concubines are pretty interchangeable. The only characters with distinct appearances are Maomao, hot fem guy, and grumpy soldier guy. Maybe the next volume will reveal why this was deemed worthy of an anime adaptation.
