This is worth watching if you love suspense/thriller dramas!! From episode 1 to 16 you're on edge and keep wanting more! The acting is powerful and soooooo well performed!! The cast is perfect from policewoman.man to killers...wow. From kids actresses/actors to adults actresses/actors...wow. And the plot, there's no 'useless episode'. All the episodes are important for the development of the story. Every second was well thought.

Watched it in two days. Now I am actually sad I've finished it so quickly!
AAAH I LOVED IT. I would definitely rewatch it.
OCN never disappoints.
