I wanted to watch this show bc of the cast first, many talented people appeared and i completely loved their acting (specially sungcheols). Now, about the story, between episode 2-5 i found it kinda boring, + i didn't like the way they added gci, it looked horrible for me. The next episodes i really was able to enjoy them bc of everything that happened and the way the characters developed. I don't know, i definitely wouldn't rewatch sh bc o think i will feel the same way, but im glad the show is having a S2 to solve every question about the ending.
