I remember watching this for the first time, I really liked it.
But to understand everything, I had to re-watch it. (That's what I do sometimes) And I liked it even more.
-------
The plot was interesting, I really enjoy watching supernaturals based dramas.
-------
The actors were great. I actually really enjoyed Ma Wang's character. I think some of his scenes were so funny to do. I don’t know how he did them. ??Amazing actor.
I also love Lee Seung Gi as an actor, he's amazing.

I'd re-watch it maybe, or maybe only some scenes that I enjoyed more??
