LUNA {The Chosen One}

For a long time, descriptions of social status or rank of Alpha, Beta, and Omega are always same. Alphas are the most dominant, powerful individuals, that the Betas are their subordinates, and the "Omega" is the lowest-ranking, the pack punching bag, who is submissive to everyone else and whose job is to take their abuse, and also to cajole the pack into play.

But Yunho, the unique omega who tried to change it.
