Kylo overhears one (or more) of the crew gushing about how attractive the General is. They go on about his hair, his clothing, what kind of filthy kinky stuff they'd like to do with the General if given a chance...
Kylo is baffled. He was never actually all that good at tell if someone was physically attractive and thus never thought about it with Hux but now the idea won't leave his mind.
He watches the General, taking in all the details about the man and trying to decide if he agrees with the crew or not.
Finally, he gets Hux alone and Force-Pins him to the wall just so he can study the man more closely (Hux is so angry about this). Kylo decides Hux is 'passable'. Where it goes from there is up to Anon.
