Years ago, Leia, Han and tiny Ben got stranded on a jungle planet, inhabited only by lifeforms that were animals rather than 'people'. Maybe Leia and Han were killed, or maybe they were just separated from Ben and we're rescued while he wasn't (depending on how sad the filler wants to make it!), but either way, little Ben was left to be raised by the beasts of the jungle.
30ish years later, a FO scouting team led by Hux arrives on the same planet, and when he manages to get himself lost, Hux finds himself getting by rescued by a strange jungle man in a loincloth...
Having not seen another member of his own species since before he was old enough to remember, Ben (now going by Kylo) is utterly fascinated. Not to mention the fact that he suddenly has a newfound understanding of what his packmates feel during mating season...
+ Kylo still wears a mask he carved himself that resembles the species that raised him ++ Kylo does eventually meet some female humans but Hux is still the one he wants as his 'mate'
If the filler would rather set this in the original earthbound setting rather than the space version that's also cool.
