My sister's boyfriend is my mate.

-Theia pov- I lived in a small town. My family was one of the most wealthy families. I grew up with everything I ever wanted, whenever I wanted. Except for one thing, or should I say, person. My sister, Alexi, was an evil person inside out. Maybe not much outside as her red hair, blue eyes, hourglass body, and petite personality attracted the attention of quite a lot of boys. But from the inside, she was absolutely rotten. She wasn't even my real sister. My family had adopted her after the old alpha, my father, had gotten in a car accident, killing both her parents in the process. Ever since she came into my family, she made my life a living hell. At campus, she would bully me with her friends, sometimes going as far as to take my car and leaving me behind to walk 150 miles home alone at night. My parents knew about everything she did but there was not much they could do as they had promised the council they would take responsibility for her. Even though she is absolutely disgusting, there is just one good thing about her. Her boyfriend. I have always had a crush on Adrien. He was also the son of a very wealthy family. He had dark green eyes, tousled hair, and oh that body. He had the body of a greek god. Adrien's father was the current alpha. Our fathers have been friends since way back our generations. I do not know how she has done it, but Alexi has made Adrien believe that she is his mate. I do not believe that in the slightest. There is no way the moon goddess would do such unjust to a person she created with extra care. I might seem like a disgusting person to lay eyes on my sister's boyfriend, but I can say that I had eyes on him first. Me and Adrien, we grew up together. We went to many social events together. Since our fathers and mothers were such good friends, we had become too. Until Alexi came into our lives and ruined everything. She knew I had a crush on him, and yet she went after him. Maybe from some way it was my fault too. I had always been shy. I could never confess my feelings for Adrien. All I could do was watch from afar as he and my sister made out, held hands, and acted like a couple. That's all I was, until my 20th birthday. The day I first shifted and the same day everything changed.
