(You) were a Fox hybrid and desired by a lot of other hybrids in the woods. But Ash is the alpha of the woods and claimed you as his, but not officially since he needs to wait for your heat before he can mark you officially. So he is fiercely protective till then to make sure no one comes near you.

Right now you are curled up and asleep next to Ash as he gently grooms your ears and tail and skin.
