Half of the series finale was dedicated to confirming with even more strength than ever that Star and Marco love each other deeply, romantically, platonically, with every kind of love there is, and that they are the core to each other’s happiness and that they know it and act on it. So it’s an incredibly deep “and they lived happily ever after” kind of finale that sears in stone the importance of their friendship and bond as a much bigger container to specifics such as romantic love and physical attraction. We can be sure that they’ll be together as long as they live and this has been built up to in an organic way that’s specific to Star and Marco but that has truths about all relationships.

This being said, I’d hug a cactus to even just have Daron tweet one (1) doodle of Star and Marco kissing calling it “canon picture from their first date ;)” or something like that, let alone a book or full length comic allowing us to see them once again (albeit without voice acting, which is a pity since that, alone, made half of their personalities).

(so I’m holding up quite well, since the finale fully satisfied what I wanted as far as Star and Marco and the almost all the other characters go, qualitatively, but quantitatively I always want more. Always.)
