Idk. I haven't really watched much of the show but I didn't like how even though Star knew how much Jackie meant to Marco and how happy he was to finally be with her she had to drop a bomb before leaving. UGH. I could be biased because I've been in that position before and it's never easy, but I'm happy knowing that they are still together and happy.
I don't think I can give a solid answer? I definitely don't have anything against Starco but i'm honestly really tired of the way it's being treated by the fandom. I feel like it's obsessed over to the point were the actual plot is completely forgotten. And it also leads to a lot of characters being treated poorly over it, Jackie in particular has been getting a lot of hate for no good reason.
So I guess it comes down to: I'm fine with it happening in the show, but I don't care for the way the fandom has been portraying it.
