I don't get the hype of this show! I watched the show while it was ongoing and sure for the first 4-5 episodes it was quite interesting but boy after that it was a painful watch till the end!.. The story seemed all over the place, the characters and their intentions did not make any sense and the romance angle was totally unnecessary and forced. There was no explanation as to what happened to the real Kang bin na as in the first episode they said that she was a lost soul and was wrongly sent to the hell..so what happened to her later on we don't know!! The Villains of the first 4 episode were interesting to watch and felt way more real and wicked than the main villains who were fought of way more quickly and easily.. Also I did not get why they had so many side characters (the people of the building), who were quite honestly irritating to watch and the angel was also unnecessary to the story.

Most of all, I was irritated by the fact that they saw/judged supernatural entities through the scale of human morals. I mean why was the ML angry at kang bin na when he knows she is The Devil! It's her Job to put bad guys away..why do he want to punish her for killing the bad guys and the hypocrisy of the ML that the minute he was the one who suffered a loss and needed her suddenly he was ready to understand everything she did??

In all I felt the plot had a lot of potential but they wasted it!.. The characters were not at all reasonable (including KBN love for HDE), side characters were not fun to watch and the plot and dialogus felt very obvious and robotic, there was no feelings and felt no emotion for the characters what so ever (they tried to make most of the characters pitiable)!...
