Undercover Kylo and Hux are so into each other that they forget it is an act and even forget they have an audience. This works out in convincing the onlookers of their relationship, but Kylo and Hux have to have a bashful talk later about their feelings.
ahh imagine them sorta realising that they don’t have to force their interactions; Kylo naturally wants his hand around Hux’s waist, and Hux can’t help the way he gives his ‘master’ a peck on the cheek every time he’s near him
but when their mission is complete and they’re back on the Finalizer, sitting in their separate quarters, it feels wrong; it feels like they should be beside each other like they have been, but both think that the other was just pretending like the mission needed them to
it’s Kylo that makes the first move; he goes to Hux’s quarters, claiming to want to talk about the aftermath of the mission but Hux can see the sparkle in Kylo’s dark eyes, the same sparkle that only appeared when Hux kissed him on their mission, when their roles were emperor and consort, not just knight and general
so Hux kisses him, pulls Kylo into his chambers by the scruff of his clothes and slams his lips against his, kissing like it’s the first and last
both hope it isn’t the last
