Moxie and Ari
I've recently watched the youtube short abou Moxie on the official JD chanel, and I have some theories.
First of, Woodcrow and Dancity High are rival schools, and Moxie and Ari are possibly also rivals, but what if there was more into it? What if Moxie and Ari are ex-girlfriends? I only have two evidences for this theory, first of, we have "Good 4 U', Good 4 U is a song about two people who broke up, one of them got over it easily, while the other (who is the one singing it, which in this case would be Ari) still haven't gotten over it, so now we know for sure that Ari broke up with someone, and maybe, that broke up was the thing that made her be her true self (as seen in Littlesiha lore video).
But why Moxie? Well, besides that youtube shorts about Moxie, I don't have much evidence tho support that it was Moxie who is Ari's ex-girlfriend, the only other evidence are their poses.
C'mon, their almost the same.
But what made them break up? Well, supposedly, Woodcrow is a private school, I think Moxie first studied in Dancity High, but then she got a proposal for a scholarship to Woodcrow, which she accepted, and because of it, she and Ari broke up.
