I'm positive that the world will have a happy ending. Though the way is kinda blurry at this point, but exciting.
SPOILER (sort of)
I really feel bad for the elves but Maria's secret reveal hit really hard. It was the most unexpected turn of events for me and really shaked my view on the world. It's also a great life lesson to not hate on certain groups out of ignorance and lack of knowledge. Some day you may be on the receiving side.
