Strangers to Travel Partners (to Lovers?)

Hi! I'm looking fics where two (or more) people meet and end up travelling together because ~plot reasons~ or whatever. And maybe by the end they can go on separate paths, but their lives are forever changed by the experience! It's like a metaphor for life! There doesn't seem to be a specific tag for it in AO3, so I ask the fanfic readers of Reddit to please, please recommend me fics that have this trope. It doesn't matter what fandom it is. Relationships can be platonic or romantic or familial. For some reason this trope is really hard to find, in fact I have only found this trope in

we can turn the world to gold by TrumpetGeek (the fic that had me all over this trope, and it has gorgeous art too) Fandom: Daiya no Ace (Ace of Diamond)

When In Rome by Getti (Epsy) Fandom: Fullmetal Alchemist

Lance's Guide to Picking Up Hitchhikers by bwyn Fandom: Voltron: Legendary Defender (bonus points for group travel!!)

you go your way (i'll go your way, too) by fakeplasticlily Fandom: Mo Dao Zu Shi (Grandmaster of Demonic Cultivation)

Only four fanfics in four fandoms! This is a tragedy. By 'this' I mean my fanfic searching skills are a tragedy. Please send help.
