Humans will be Humans, it's either you trust them or you don't. This drama was filled with action and very entertaining however i would have preferred a different ending.

Looking back from episode 1 all the way to 16 I would really like to applaud Gu Reum, this incredible woman was a hard worker, persistent, stayed true to her self and a very good fighter, however I honestly think she was never genuinely happy. What she didn't realize was that you can't change people, people only change if they choose to and on their own terms and free will.

The fight for justice for her parents, being left alone from a very young age and the battle of being alone and lonely was all too much for her. I was deeply saddened by the way things ended for her. The little happiness she got was quickly taken away from her.

Zi-0 being born by a form of genetic mutation and genetically modified was incapable of feeling emotions until he met Gu Reum and like her he was alone & lonely and even more so always on the run escaping death.

I believe things would have ended differently if he went through therapy, to me he changed his perspective on life again because he was never free from the mental chained state he was in since childhood and then meeting the same people again who put him through hell, calling him a monster led him to believe that that is who he really is.
To free yourself from mental slavery, you must go through a form of therapy, sadly he did not and the result was a reflection of that.

People will only cry help and say they're changed only when death are at their doors, humans are evil selfish beings that worship money and just like those from the drama they lack humanity and never changed.

This drama is a little gem, there will be frustrating scenes that will have you wanting to drop it but I personally think it's worth a try. Not a ending I was hoping for but it is what it is and somewhat realistic.
8.5/10{overall}
