A one-sided intrinsic urge to fuck is still kind of soul-bond, although honestly it was more common in the kind of soul-mark/first words your true love will say appear as a tattoo on your skin sort of fic than the traditional soul-bond we are antagonistic but destiny has other ideas fic. Or it's just a fuck-or-die variant with a repeat situation novelty. Fuck-or-die is still pretty popular in some comics fandoms!
