I started watching because the cast guested on Running Man and finished it in one sitting. The script isn't as good as I expected it to be and there were times when I had to look up stuff because it wasn't explained properly but what made it worth watching until the end was the cast... The entire cast is S T E L L A R. They were so good that I ended up rooting for every single one of them... and every death pained me in ways I didn't imagine (especially "that" man who was warm and kind and understanding... he was decent and consistent throughout so it hurt me alot). I was also taken by surprise when I saw Kim Sung-cheol (my Prison Playbook babies reunited ♥)!! I will be looking forward to the second season because I now have so many questions that I want answers to lol
