Arranged

Hiccup and Astrid are arranged by their parents when they're 14. He's happy, she's furious. She spends a year taking her anger out on him and making him miserable. No longer willing to marry her and tired of being Berk's punching bag, he leaves after he heals from the fight with the Red Death. When he finally returns, he's not what Berk was expecting… and he's not alone.
