A story of two people who met and after a while they fall in love but Hiccup is already going out with Astrid and she doesn't like sharing her man

[Older!Hiccup x Fem!Reader] Nobody could anticipate that a relatively small village on Berk would completely shatter the ways of the Vikings, especially someone who spent most of their life living in it. It's been five years since you last set foot on the island, and the surprises awaiting your return would overwhelm anybody. Except maybe your old best friend who just so happened to be the one who started them all.

Tales of a woman who has tamed and trained an ancient dragon have spread throughout the archipelago. She is thought to reside on the western coast in the village of Sadur. Hiccup and his crew are skeptical, knowing that vikings tend to exaggerate and whatnot. But one day, Hiccup and Toothless come across a new visitor at Raven's Point with an injured dragon. Is she....the one they've truly heard about? Read about (Y/N) and Hiccup, and how their encounter will affect the rest of their lives.
