Was it just me or was the whole last episode filler and flash backs?? nothing happened until the very last fifteen minutes. also how the heck did Noh Seok Min even survive??? I was expecting him to become a demon somehow. but he falls of the tallest building I’ve ever seen and falls into the water and somehow survives?? falling from a height like that would be like hitting cement and absolutely shatter his body. he comes back for all of five minutes and is dead ? it would have been more completing and exciting if he had come back as a demon as well. that’s where I thought the show was going with him stealing the book and learning about demons. that all became pointless then too.
