I had many expectations for this show because of the director (Extracurricular, My name) and because of the cast, but unfortunately I was disappointed. The plot was a little bit childish and not convincing. There was no suspens at all and I wasn't looking forward to binge watch this show. I'm not quite sure if the problem was in editing or in the direction in general. They forced a love interest between the two protagonists in the first episodes which blow out really soon through out the series. The bigest surprise though was the acting. O had a feeling of overacting. Although I really enjoyed Choi Dae Hoon's acting.
