Where have you been

So this is my first story pls no hate, thank you

In this au, instead of taking 3 months to get back to the Isles, it took 3 years which would make him 16 and Matt 17. Meanwhile, back at the Isles, Matt was very worried about Gus. Gus had been the only friend Matt had, and he didn't have a clue what happened to him.

Warnings at the beginning of each chapter , also if I make or if you read any of my books, my fav character usually has the most angst
Soooooo get ready for some dramatic Matt angst because, why not?
