You Are Mine, Omega

Allison fell in love with Ethan Iversen, the soon-to-be Alpha of the Moonlight Crown pack. She always wanted him to notice her. Meanwhile, Ethan was an arrogant Alpha who thought a weak Omega could not be his companion.
Ethan's cousin, Ryan Iversen, who came back from abroad and was the actual heir of the pack, never tried to get the position nor did he show any interest in it. He was a popular playboy Alpha but when he came back to the pack, one thing captured his eyes
and that was Allison.
