A masterpiece! It's a very good show! It's simple!
I can't forgot the funny scenes, I laughed so many times! There is a good chemistry with every characters. There are action scenes and plot twists, through several cases that are well structured throughout the episodes.
Initially the story goes a bit slow, like him LOL! But every situation helps him to evolve, and gets to the most important part...
However from the beginning he proves to be a zombie only with his body (Choi Jin Hyuk has a really good body!) and he's more human than a real human, he feels emotions and common sense.
Showing how in reality the world is populated by different monsters who are none other than human beings ...
There are also romantic/cute scenes but not too much so it's perfect for everyone!
I don't know if they are thinking about a 2nd season but it can be cool!
Thanks for reading me! ^_^
