basically, a bunch of demons + a main character that became stupid over time = 21 episodes of no redemption nor catharsis kdrama

It's like a waste of time watching this since no character developed for the better. Almost 24 hours of your life will be drained for nothing since no redemption nor catharsis happened. The story itslelf is over the top. The characters are comically evil. The main character who was presented to be smart suddenly became stupid at the last minute. This show is so frustrating to watch. Glad I watched it at a higher speed since the story progressed for nothing. That ending was disappointing.

The only good thing with this drama is the actors. They saved this from going down the drain.
