First of all, don't get me wrong. I do like Lee Jong Suk and Han Hyo Jo. They are one of my favorite talents. But this drama has too many loopholes in the story. I cannot find myself to like both of the main lead and neither I can find their chemistry at all. I find the romance is being too forced and does not make any sense at all. For example like the true main heroine of the manhwa So Hee, how can she get pushed away by a mysterious girl that just show up? The writer is very sloppy in creating the plots with a lot of unexplained things like why the female lead was summoned in the beginning and then the no face killer. And how come the no face killer has awareness? I thought the story focuses on Kang Chul? I also find the story is also being dragged too long with so many weird romance filler. I mean the manhwa is a mystery genre, but then turn to be a really weak mystery genre. I don't feel any suspense at all. I find the idea is nothing new and not all that groundbreaking (maybe in k drama this is the first time about cross world manhwa theme but the plot with the no face killer thing, I find the plot is easy to recognize). I find myself being really impatient and skip so many scenes.  -______-" I know this drama is a hit but at the end, I just can't find myself liking it.
