Emperor Hux takes a wife because he needs to secure his dynasty and produce heirs. The relationship is purely a business deal and he has no feelings for the woman whatsoever but Kylo feels insecure because she's very beautiful and can give Hux something he can't. Hux has to reassure him... and ok yes this is just another thinly veiled Kylo Ren praise kink prompt. I just need Hux snuggling his boy and telling him not to worry and he's still his favourite.
