What can I say to give this drama credit? There's nothing, nothing. It was beautifully executed from the filming to the script to the attention to details. It never left you leaving an episode without wanting to come back. The cast my god the entire cast was brilliant. The leads the good and the bad were exceptional in their roles. The side characters were never just written in as fillers they made the story what is was. It teaches us so many lessons the top two I learned were - Never give up ever, you can change the future and that you can't change everyone's fate you can't save everyone. It definitely had many other touching quotes like every handcuff is worth 2.5 liters of tears. It showed that through corruption there are those to succumb and become dogs to the ones in power and there are those who fight back so that the innocent won't be hurt. I highly recommend this drama for those of you who are in a drama slump or are into crime and mystery dramas.
