I'm not a shipper but I would like Starco to be canon, HOWEVER!
I don't want the relationship with Jackie to end abruptly like her character and feelings don't even matter (inb4 "plot device lol"). Secondly, I wanto to see how Marco and Star's relationship (i.e. their friendship) will evolve with rhe new informatiom both of them now have about eaxh other. Finally, if Starco becomes canon too early I feel like it may crumble towards the end. Their relationship, in one way or the other is going to be relevant to the plot, so I would prefer not to see hasty steps.
