Korrasami is the best one, and most importantly, is the only one that really works. Korra and Mako’s personalities don’t mesh well together. They’re good as friends, but as lovers, they just cause problems for each other. They just don’t work. Korra has no feelings for Bolin, and their personalities work better as friends (also Bopal is cute). Meanwhile, Asami is patient, kind, and empathetic. She is what Korra needs, and Korra is what Asami needs.
