Omegas are the lowest in the rank. And they are the most who are bullied and often times harrased, s*xually and emotionally.
Eventhough she was born on a pack that the Alpha doesn't descriminate the Omegas. He still can't stop other pack members from bullying the Omegas. And does she needs to stand up for them. She knows she can make a change. Because even if they are Omegas by rank they are still someone that is important to the pack and she's willing to change it.
But could she still do it if his mate despise her as an Omega?
