Anything with these two being really close friends. Finn is what unites them, but gradually their relationship morphs into something else entirely. Secret handshakes, in-jokes, roughhousing, playing games, etc. In my mind it's normal to see them pass through hallways bickering, or to high five each other without looking when one of them says something funny.

I love the idea of them as BFFS, maybe with Finn/Rey as a main pairing but not necessary at all, Finn/Poe or gen are also <3
