okay, this drama is quite hard to rate tbh. at first i hyped this alot. ep 1 and 2 was written really well , you can't deny that. but the progressive eps were kinda draggy, it seemed like there were alot filler eps just to fill in for the 16 ep gap, and they dragged the main plot out for too long, there was nothing new and it was still the same trying to seal the demon, including some obstacles here and there. there were times i was invested, yet there was times i looked away. but i have to say the plot is good, it really is good and very fresh but the con is they dragged it out for too long. this is easily one of the best sageuks if they didn't drag and filled in filler eps, but nevertheless, it was still enjoyable, but kim yoojung gets a bonus point from me. 9/10
