My Bestfriend is my Alpha and Mate
Alexis Whitman and Ash Baker were close when they were growing up considering the fact that Alexis was the daughter of the beta and Ash was the son of the Alpha. Ash was always very protective of Alexis and so was her brother because little did she know that Ash was her mate.
So when Alexis left to go on Student Exchange in London, it torn Ash to pieces because the of the distance. When she left he had stopped talking to people, very rarely ate and he locked himself in his room.
Two months later when Alexis turned 16, she was sent home to her pack due to the tremendous amount of pain she was in. When she got home she saw the terrible state Ash was in and as soon as she saw him she knew, she knew why her attraction was so strong towards her bestfriend.
