Hux has a nice little apartment. Life is good. That is, until Kylo Ren moves in next door. He doesn't actually SEE Kylo at all, but boy, does he hear him. From drilling and sawing at 3am, to screaming arguments when his parents come to visit, to hearing him having what he presumes is really depraved sex, Hux hears it all.

One day, he snaps and knocks at Kylo's door.

And guess what? Hux takes one look at him and thinks, oh no, he's hot.

a happy (and filthy!) Kylux ending preferred, but I'll leave everything else up to the author!
