Grateful to Typechap for this appealing Anadalucian billboard.
Here's a sad Sonamy AU: Years later, Amy has move on from Sonic and only sees him as a close friend. While he just does his own thing, he ends up falling for her, but nobody knows this and he fakes his way through. He helps Amy and she ends up marrying, He's sad but still can pull off a smile. She asks him to dance but he despises slow dances, she offers to teach him and he gives up. Some blushy moments later and he accidently confesses his love for her. What's next is up to you. ;) (Not Boom)
