Huh, it's hard to swallow how human nature turns out in difficult situations. I really enjoyed this series, but I constantly felt I wanna punch in the face most of the characters. I just can't believe how some people are able to hold on to their status when the world is collapsing and money is meaningless. The main character's development is kinda slow, but it matches the rhythm of the story. I can recommend this series to those who like zombie/ monster/ sick stories like Train to Bushan, All of us are dead or Sweet Home.
