So the drama was pretty good. It had a good & unique story. But after first few episodes the drama goes into being typical crime solving mystery drama's. You will understand what I am saying after watching it for yourself. Though this is not a bad thing. Many people do like this kind of drama's. But it kind of feels lengthy in the middle part of this drama. But not so boring that you will drop it. Actually if you get into this drama you can't possibly drop it before watching the end of it.
All the main cast's did a great job. But few side characters were a bit off with acting in my opinion.
Now something about the ending (Spoiler free)
I think about 50% people who watched this drama were satisfied with the ending. And the other 50% people weren't satisfied like me. I mean the ending didn't make any sense to me. It was good but also bad.
This drama is definitely worth watching. I watched 4 episodes per day. It took me 4 days to finish this. If I wanted I could have finished it sooner. If you are into mystery, crime, thriller this kinds of drama then you won't regret watching it.
