In terms of plot, this has got to be one of the best suspenseful drama I've seen. I love dramas where you can't easily predict what's going to happen next. It makes you think one way only to find out that you've guessed wrong. The writers know how to make an audience viewer long for more because that's how I felt every week watching 4 episodes. Don't know why ratings are low for S. Korea viewers. I think they tend to miss out on good dramas a lot in my opinion and like the dramas I considered as poor.

We got a strong male and female lead. At first it seems like they're just vulnerable weak characters but don't let that fool you. They are intelligent and once they have a focus on something, they go through with it. A little bit of comedy and a little bit of romance but honestly that's not the focus of this drama so at times it throws me off when either or happens in this suspenseful drama.

The problems I had is that they tried to show a small bit of romance but never went through with it. I mean even the ending seemed like there was some sort of spark. I rather not have the romance at all if they're not going to go all the way with it. That kinda ruined the ending for me a bit even though it was a decent ending. Though this did wrapped up all of the loose ends of this drama, I think they stalled out this problem too long, making the last 2 episodes felt very rushed.

OST Music is good. The only bad part is you've rarely heard any in this drama. This drama isn't bad but mystery solving dramas aren't re-watchable for me because I know what happens already. It's only good for a first time viewer of this drama. Overall, I think you'll like this drama if you're into crime solving suspense dramas. Just don't expect a lot of romance or humor from this drama.
