Kylo Ren:

Lindor chocolate truffles, he loves to share them with you, especially the white chocolate strawberries and cream flavour lindor truffles. He likes 3 different flavours, strawberries and cream, mint and orange lindt truffles. He says they are delicious, and he got onto them when you offered him one of your chocolate truffles. He was in love with them ever since.

Hux

You both love Australian made red licorice, (not to impugn his hair colour.) He says that red licorice is tasty. Also said it tastes of red cola.

He loves warheads sour candy he's a fan sour candy fan. You got a laugh when he eats these because they're sour, his face starts to screw up due to their sourness.

Luke Skywalker:

He's got a big affinity for hard shelled, chewy candy, especially skittles, he doesn't like this purple ones though, he gives them to you, you like that about Luke.

Finn:

He loves to share his affinity for chocolate coated salted caramel with you, he loves the stuff with a huge passion.

Poe Dameron:

He loves caramel and peanuts, so his "candy" of choice is payday bars, he eats one before flying off on a mission to beat the First Order.

Han Solo:

A smuggler like Han has an affinity for anything with peanut butter in it, so you always stocked up the Falcon with his favourite in flight smuggling run snack, Reece's Peanut Butter Cups, you can't stand them, but had to tolerate it for Han Solo.

Obi-Wan Kenobi:

He's such an old school sweetshop classics guy, he loves fruity hard-boiled sweets, he can whittle them down in size by sucking on them before crunching them. You only have one every once in a blue moon of course.
