I am not against the ship at all but can someone please tell me where Hux/Poe is coming from? Is it based in the real people who play them's relationship??

It seems mildly popular so it's going beyond rare pair status. Just curious, the movie is not fresh in my mind but I don't remember Hux and Poe ever even stepping foot on the same planet. (Although they were both on the ship when Poe was captured, I guess?)
