I just finished watching this drama and all I can say is that it left me with a lot of questions. I even searched if they will make a season 2,but that is not the case.Overall it was a very good drama and I recommend it to anyone who likes dramas that focus on crime and psychopaths and not so much on romance.

1. I have read a lot of reviews on this title that were complaining about the romance between the main leads,or lack thereof.The interaction between them felt like a breath of fresh air next to the crimes and investigation that was going on.Quite frankly I liked that.It was the right amount of romance this drama needed.It was like a little part fitting perfectly between the whole plot.
2.I have nothing to say about the cast because it was magnificient.Everyone played their parts very well!
3.I loved the friendship between the investigation team so much.
4.Now to complain a little.Why did they have to finish the drama like that?It left me very confused.I think it would have been better to end it with catching/killing the murderer.I literally scremed when it said that he disappeared.I could have understood the ending if they would have done another season.It's like I got to the end but the story was just starting.
Another thing:I like how they ended the things between the main leads BUT what about Min??? Personally I think he chose to live as the real him but that is just my opinion.Still...what happened to him?Did he get arrested?Did he went to the police and confess? Even before this. I thought he died but after an year we see him in a hospital... What happened there?
When Hyun met for the last time with Jun Yung, why didn't he arrest him?He already told Hyun he will leave so..It's like he wanted to chase Jun Yung for all his life.Last but not least how did Hyun knew where Min is and that he is alive?

Even after all of this the drama is very good and it deserves more recognition plus I really adored the bromance between the brothers. This drama also keeps on a leash,meaning that the plot is too enteresting to make you want to think about other stuff.At the same time it makes you have so many conspiracies about what would happen next.This makes the drama so much more entertaining and captivating.Please check it out :)
