finn lives next door to you and you are five years older than him

he is 10 years old and you are 15 years old "before"

he told you that you have to promise him that if he is of the right age you will marry him

you just said yes because you thought he was just a child

until finn moved to another country to study at another school, you didn't see him again ten years passed untill..

you were walking down the street when someone hugged you from behind you turned around and see the handsome and tall man hey my future wife, i'm back..
