gentleman-caller:

Kylux ‘saying “I love you” without any words headcanons:

– Kylo kissing the sensitive spot just under Hux’s ear before he leaves their quarters in the morning

– Kylo barely placing his hand on Hux’s lower back as they stand on the bridge together.

– When Kylo comes back to the Finalizer after some strenuous ordeal, no matter how fruitless the outcome, Hux has a meal waiting for him and the time to help him undress and ready for bed.

– Hux tending Kylo’s wounds himself  

– When Kylo wakes from a nightmare, struggling with the sheets and covered in sweat, Hux is already holding him. 

– Kylo slipping his arms around Hux from behind and resting a chin on his shoulder.  Hux reaching back to tweak his nose.

– Kylo distracting Hux from his work when he grows too anxious, too obsessive.  Kylo fondly pulling his co-commander card to order Hux to stop and spend some quiet time with him.

– Hux wishing Kylo well before he leaves the ship with Phasma and her team.  A quiet, unnoticed squeeze of his hand says everything they cannot say in front of the crew.
