I was pretty scared to watch this series because of bad reviews what I read but honestly I'm glad I watched it because I really like it. I liked how there were two main storylines that were connected. I honestly preferred the Sky and P'Pai's story but maybe because it took me so long to get there and I kinda forgot what Rain and P'Payu went through...
I definitely recommend watching it, maybe just as an advice, watch it in a smaller period of time, not like me who didn't have time so left a big break in between some episodes and then didn't know what was going on :)) Definitely planning on rewatching it.
