I know it is a mid fantasy drama, so I will take it as an entertainment only.

The drama gave a lot of backflash to make you understand the context as they don't reveal it directly after a scene and make you in questions sometime.

Firstly is rather slow pace, but it keep it faster towards the end and a lot of twist here and there. I think some questions is not answered yet, but okay.

Lee Hani ofc carried the show and yes, I'm a fan of her. I watched her Fiery Priest and also Extreme Job and she is always excel in those comedic role. Perhaps this is her comfort zone.

I agree it get the hype on the local and quite deserved. And if you want fresh comedy, you can give it try!
