It isn't the worst thing ever, but it also isn't particularly enjoyable. The storyline was pretty good, but I feel like the execution and the screenwriting of it wasn't so good. There wasn't a single bit of comedy to relieve the tension,

Firstly, I don't think any of the characters really had any substance to them. They all had the same bland personality, and I didn't feel like I could relate or sympathize with any of the characters. Usually visuals make up for the lack of acting but in this one, neither were present. The circumstances are not extremely unrealistic like other kdramas, but the way they reacted to the situation was out of the ordinary in neither a good or a bad way.

Overall, I do NOT recommend unless you are looking for a brainless quick binge.
