Excellent story, art, and characters!
Plot: This story is a masterpiece! It's been so long since I've seen a story so well-written with a well-developed plot and characters. Everything is so well thought of, the author did an excellent job studying background information on herbs, medicine and many other topics which made the story so much more interesting.
Characters: The main female character is honestly smart, knowledgable and quick-witted. She can handle pitty schemes all the way to murder cases perfectly. I also really like she isn't swooned by the main lead, instead, he's slowly falling for her more and more along with the rest of us.
Even the "villain" characters have a well thought of story behind them that shows the flip side of things and how people can be bad and good at the same time.
