In the comic Homestuck, there are humans and trolls. Trolls are driven by two primary emotions (hate and pity) and have a very weird relationship set-up. Here is the real explanation: wiki, comic. But I will sum up!
There are four primary relationships in their romantic lives and the best result is to fill all four quadrants simultaneously.
Red romance has one sexual quadrant (your matesprit, for whom you have "mating fondness" - the closest equivalent to human romance) and one platonic quadrant (your moiral, who's "fated" to keep your ass in line and watch over you). Black romance also has one sexual quadrant (your kismesis, with whom you have ALL THE HATESEX - the point is a rival you hate and strive against, but will never/can never kill or defeat) and one platonic quadrant (your auspistice, who mediates between a (you) and b (someone you hate) to keep the ab relationship at a functional level).
