During a freak accident on an alien planet, Kylo and Hux end up being pair bonded. The bond is for life.
Neither of them are happy about this. Being away from each other for too long causes stress/anxiety/eventual pain, they can feel the other's emotions and thoughts (something that's new for Hux, at least), and there's the almost overwhelming urge to throw the other on the floor and fuck their brains out.
They're fine with satisfying that last urge with plenty of hate sex... except it's hard to keep hating someone when you know almost everything about them and now understand them so completely and utterly.
+++ Neither of them realize they've fallen in love until they're really, deeply in love.
