AU where Luke is a slave, but not the sex kind: Jabba remembered the name Skywalker and tried him out at podracing. Now he's traveled all over the outer rim to race on different worlds, he's been the reigning champ for years and is a minor celebrity in the region, and none of it is worth shit because he has a slave tracker planted under his skin and will never see his family again.
So when Han meets him (...somehow...) he's actually the wordly and jaded one. What does he care about who wins the war? His situation won't change either way.
Luke/Han, slave!Luke
