I think this is new fresh concept of the KDrama, it contains many genre : comedy, dark jokes, fantasy, thriller, jump scared, romance, melodrama.

The casts was soo amazing, the characters also interesting and makes me wondering what are they true colors.

I really enjoy this drama, because it was really funny and yet makes me wondering what happens next. The plot was unpredictable. This drama likes to clowned us a lot.

The pace in the early episodes (1-3) maybe lil bit slow and some said it was boring, but I think the first episode was the important thing to lead us know what happened in the next ep and why they're all doing such crazy things.

So far, it gets better and interesting in every episodes. My feeling just like a roller coaster whenever I watch this drama.
