I think the story had a lot of potential, I´m usually up for a fantasy, but somehow it seemed wasted, chaotic, superficial, and with many boring long scenes. I liked the cast and hoped for some twists, but it did not get much better even in the second half. I haven´t read the webtoon, it might had explained a lot. The whole drama processing was very manga-like. Cha Eun Woo was my main reason to finish this, thought his charater and his abilities were a bit over the top. As a rating I decided for 7, still I was quite disappointed, and I wonder if the open ending will be of some use in the future.
