On That Distant Shore || (Adventure Time) Finn X Reader

(CROSSPOSTED FROM MY QUOTEV ACC: @mochacoma)

Finn, the last human on earth.... Or so he thought. Meet (Y/N), a human that can't seem to remember anything but their name. They washed up on the shore of a beach one day and were lying in the sand unconscious. When Finn walks through and sees them lying there, he doesn't know what he's in for.
