Before Kylo came to the Finalizer and was made to stay, Hux had had to accommodate every single Knights of Ren who'd on board the ship per Snoke's orders.
(And I do also mean "accommodating" in a more...fraternizing sense, yes.)
Maybe it could be a 6+1 fic (how many Knights of Ren are there again?). Hux ends up sleeping with all the Knights who came to Finalizer, one by one, but Kylo's the one he actually stays with in the relationship.
