I wish I could make Korra x Ginger popular. You can. They are cute and sexy in my opinion.
Maybe we can together! I love this ship, but right now the only two endgame Korra/Ginger stories are mine. Why don't you make one, too? Or make some art, or even just post some headcanons or edits or a playlist? I'd love to see your take on the pairing, and it's not like I'm a BNF or anything so there's no difference between my making stuff for them or you. There's even @atlararepairmonth coming up in only a few weeks if you need some prompts to spark ideas.
I'll tell you honestly that a Korra ship that's not Korra/Asami will never be popular in this fandom, that's the sad state of TLOK shipping. However, small ships can absolutely attract a dedicated crew of lunatics who love them and there's no reason Korra/Ginger can't be one of them. But for that to happen, more people need to see the vision. I can't do that alone. No one can. Fandom is community.
For starters, they're gonna need a ship name. What do you think?
