Hannah:
I have a theory
(re "Your Sky") Yes, I think so, too. Given the way episode 1 confusingly dumped us into the middle of things, without the orientation scene (as in the trailers) or various other background explanations (e.g. regarding the name "Saggy Checks" - indeed an irritatingly stupid nickname, at least in the English translation), I think subsequent episodes will go back in time and reveal these things, including your theory.
I don't think this is the ideal way to unfold the story, but Kong and Thomas are so good - and that makes up for a lot. As often with Mandee (and to a lesser extent also GMMTV), one watches for the cast and characters, not necessarily the story and execution.
