The story is so fast-paced and the moment you anticipate it to follow a certain trajectory that most sageuk dramas would, it defies your expectations. The acting is so precise, especially from the ML who has a very expressive face and portrays multiple emotions and two personalities distinctively. The fight scenes are quite well-executed too, love the FL's parkour!

The entire ordeal of the ML having two identities approaches very close to discussions around dissociative identity disorder. Although portraying it as an evil spirit entails misrepresenting a stigmatized mental health disorder, I think in the historical context it is still very accurate since medical research had not expanded on it back then and many disorders were confused with spiritual possessions. I like that the drama could express this type of narrative so well.

Watch this drama, if you like:
- Main leads defying gender roles
- Good fight scenes
- Witty dialogues and communication between characters
- Fast-paced stories with cliffhangers in every episode
