I liked this. My main problem was that I liked Hyun Soo on the top floors once he and the rest got to everyone on the main floor it fell off for me. It was still interesting but not as much. Like at the beginning I loved this then I started getting bored of it kinda. The plot simmered down after they were all on the main floor, there were still things happening but it didn't make me wanna keep watching like before. But other than that I really liked Hyun Soo, he was a very interesting character to me. One thing that surpised me was when that religious guy had a sword like I was caught so offguard.
