The Werewolf's mate

Kiora lives in a world of different species. For example she is an elf, one day the boy who used to live next to her, returns after leaving suddenly two years before and seems like he hates her. Kiora doesn't question him, assuming it's because she is an elf and he is a wolf. However, will she find out there is a different reason for his seeming hatred? Not only that, she has a past that she has yet to uncover.
