Lmao I ALMOST reblogged that same post about show writers never making gay ships canon/ endgame with the tag "um korrasami?" I'm happy you thought the same
Korrasami is a prime example of the creators taking advantage of the potential a gay couple can have instead of denying it or shying away from it.
I mean, back in season 1, Mako and Korra were supposed to be the endgame. No one thought that Korra would have more than one season, after all. But by the time season 2 came along, they thought it better and decided that Mako’s relationships with both Korra and Asami were doomed to fail, so they just ended the romantic triangle right there (which was a relief).
But by the time season 3 came along, with Mako no longer being considered as a possible romantic partner for Korra by the crew, they started to realize that Korra and Asami had developed a strong bond and understanding, and that this strong bond could be developed into something romantic.
Which they really did… although not as explicitly as some people would like. But the buildup is very obviously there, and it payed off pretty well, imo.
…Unfortunately, though, Korrasami is the outlier here and can’t be counted. Shows with gay pairings usually already start with that part as a defined aspect of the show (like with Steven Universe). They very rarely organically develop a main gay pairing like this one if that already wasn’t the plan.
