StarXTom is definitely going to be endgame, and I've got proof.
So, Star hates wood, right? And naturally that's why she hits a tree to let go of her anger. Meanwhile, Tom is doing the ritual to let go of his ANGER.
But at the climax, at the same exact moment Star expresses her most feral rage against that dirty tree, Tom burns a whole bunch of them.
You see? Not only to cope with anger they both instictively bullied wood, showing they are intimately similar (as anger is the powerful emotion that reveals the thruth about yourself and your feelings), but they've even dealt the final blow exactly at the same time, showing the perfect, natural and intimate bound between their souls, as the bursting inferno symbolized burnuning desire or some shit Note: blue flames like these are hotter - see: stronger - than red ones, since artificial bounds like the Blood Moon ones are weaker, "redder" than the real thing.
Oh yeah, Star also hugged and comforted Tom or whatever.
For real thought, I liked to see Star punching wood, that's some nice attention to details
