alpha's rejected beta mate

Lucas rejected Stella and banish her from the pack. her brother and mate both left her alone to fend for herself in rogue world. she is now rogue after get rejected. she is also very vulnerable because her wolf refuse to show after loosing her mate. without her mate and wolf she is now like a death human who is wandering in forest just to live until she die. no one cares for her now and she is now about collapse in the heart of northern forest area when she found an abundant cabin. she found hope to get help but when she reach there it's empty.
sitting at the cold floor of cabin she thinks of the incident happen with her before she left pack.
I, Alpha Lucas Derrain, reject you, Stella Murphy to be mate and futer luna of crystal moon pack. may this bond severe to forever never to bound again.
what are you looking at? do you think a pathetic mutt can be my mate and luna of this pack. a murderer cannot be a good luna for me and now leave from this pack before morning because I do not want to see your dirty face here anymore. I, alpha of this pack banish you from now onwards.
his alpha command shake Stella and that moment her wolf howl in her mind and left her alone to bear with all this.
she turned towards her brother for help with tears in her eyes and pain on her face but what she saw in her brother face has turned every hope in her to jump out of the window.
disgust... yes that was the look her brother Aston Murphy has on his face while looking at her face.
Hey lovelies, how are you doing? she chirping while coming to the office of alpha without even announcing and jump on Lucas lap like and lapdog and started kissing him to which he doesn't resent. this give Stella her queue to leave because this betrayal gave her pain and not only this even her brother also kissing another girl from the pack.
