highway to hell
When Gray wakes up one night with a voice in his head, the last thing he expects is to suddenly be sharing a body with a demon. Natsu is nothing like Gray expected, though. He's surprisingly charming, and more concerned about getting Gray to eat vegetables than he is with taking over the world. Since Gray can't push him away like he does with everyone else, he begrudgingly accepts Natsu's place in his life - for now. But when Natsu ends up needing Gray's help, what started out as an inconvenience turns into a road trip - and a friendship - that changes Gray's life.Cross-posted on AO3 and fanfiction.net as splendidlyimperfectFind me on tumblr as @splendidlyimperfect…
