Another drama with a post-apocalyptic genre, but this is K-drama, really rare to see K-drama with a theme like this. Overall not bad, good character, good story. But there is two things that take my concern. First, because it is adapted from the comic, there was some scene that, for me, to "jump", it's like you change from one scene to another without a proper explanation. Second, for a serial with a monster theme, it's less scary and frightening, I hope to see more horror and gore with this kind of drama.
