I must say that the title and the first episode deceived me as to the content of this series.
I thought that this would be a more light-hearted series with interesting cases, like the one in the first episode, cases that actually could be considered psychological.

Mostly, cases in following episodes were based in familial conflicts, poisoning etc. -- they also felt samey after a while.
I did not care for the court intrigue at all, and so I needed about two months to get through the second-to-last episode.

I also wished that we got to see more of Gye's family, I think the characters could have been really interesting but they remained rather one-dimensional. Overall, I enjoyed the interaction between the family members.

One last addition: The poisonous plant ("Dansacho") shown seemed to be Cyclamen, which is native to Europe and to the east up to Iran, NOT Korea. If it is, the symptoms are not what characters experience in the series. That fact makes me question the reliability of other medical practices in the show.
