I love this show so much, it's a five star, nothing could beat it in my opinion, I've finished it 4 times already but I don't care. I always rewatch it, the only problem for me is episode 6, I find it very sad and I always cry in it watching Ali and Ji-yeong dying, I know she was in only like 2 episodes but I still liked her. I also hated watching Sae-byeok die.
