I can't on good conscience give this a good review. It was so all over the place that I forgot what this drama was all about. There was too much stuff going on. I was so confused on the betrayals as well. If you betray someone, how could you be friends with them? At some point I just gave up. Too many names doing different things that made it even more confusing. Plus as I mentioned before I'm not good with names so that made it even worse for me. There were too many times when the enemies was for and against the main character. I'm thinking where was the writer going with this? It was like different ideas hit them and they just included every idea they could think of and put it in this drama.

My main question was this: why would you agree to go into a prison where you can't protect yourself? It seems like anybody can walk into a prison and stay there if you live in Korea.
Once the main character realized he couldn't get what he needed he should've left but it went on to another plot and then another, and then another. By the time the episodes progressed the main plot was forgotten until the 15th episode.

I was going to drop this but I don't have anything lined up. I caught up on all my regular shows which are in hiatus until the fall. There are several Kdrama sequels that will be coming out that I'm waiting for: Fiery Priest, Uncanny Counter, First Responders, to name a few. I've been looking for something to fill the void until then.
I already dropped two dramas but I stuck this one out.

I will give the revenge factor a 10 though. A lot of bad guys got what they deserved which made me happy. There was some unfinished business though. With the way each episode dragged you would think all the loopholes that happened within the 16 episodes would be covered but they weren't.

It look like a sequel will come out but I doubt it. If it does I know I won't be watching it.
