I LOVE this drama. At first, I'll be honest, I watched it for Shige, but this turned out to be a suberb drama. The characters had depth and the story never dragged because each episode was a different character's story. As the story progresses, everything starts to become more clear. It feels real while at the same time being a different crazy kind of universe. In my opinion, this drama is under-rated. There is also a hint of romance too. And while it is a mystery and a suspense drama, at the same time, it is freaking HILARIOUS! It felt very refreshing to watch. I also loved the ending song by NEWS. It's actually my favorite song by them now. The only reason I wouldn't watch it is if you are the kind of person who gets scared, creeped out, or disturbed easily since there are some scenes like that. It's defiantely worth a watch or two!
