I loved what they did with this one!
Having read the webcomic prior to watching this one might have helped me to get into the story more easily, but it surely was not necessary; meaning that even if i had watched this without reading the webcomic i would still give it the same rating i'm giving now.
The acting is great. Specially the main leads. The kissing is a bit awkward the first time but nothing that will make it impossible to watch this drama.
I specially loved what they did with the character of Denis. In the webcomic he is very much different but i like the drama version way better. It gave a new and different meaning to him and his actions.
Overall, i think this is a nice drama with a fantasy-like thematic that may not be everyone's cup of tea, but it was mine and i loved every second of it.
