Aside from Kim Se-Jeong and Joe Byeong-Gyu, the reason why I get interested on this drama was because of its genre plus it was produced by OCN. The story line and plot was new to me for this genre because normally, a crime was solved by Police but in this story the Counters are the front runner in catching the culprit possessed by evil spirit before handling them to the Authority. The suspense and trills in watching this drama was not that intense compared to a normal crime drama but you won't mind it since the pacing of every episode, the editing and the effects made here was superb plus the Actors were really great. 2 thumbs up .........
