This is for an AU where Hux is a fox trickster and Kylo a dragon. Their marriage was arranged when they were still very young but the actual wedding doesn't happen until they're both way into adulthood. At first they're both miffed because Hux had a life in the human world while Kylo would've liked a dragon husband instead. But then Hux shows him how he can transform into many a thing, a dragon too and Kylo is suddenly charmed.
