The Cullen's were a group of attractive vampires that were hundreds of years old. It consisted of the parents Carlisle and Esme. And then their adopted kids Edward, Alice, Jasper, Rosalie, and Emmett. And then recently Bella had came in the family. And they were extremely close and like they wanted Bella to fully time be there. But Edward didn't wanna bite her yet. Yada yada.

you were Bellas sibling though. You were younger and you would come over almost everyday like you practically lived there. Like alice had made a whole ass room. But you didn't really interact with anyone. You were quiet. Didn't like to be messed with. So, nobody knew you like that. That included Bella. And she was your sister. So, people kept trying to get to know you. But unlike Bella you didn't give into that.

Unfortunately Bella went to James who trapped her in her old childhood ballet studio. And was getting absolutely fucked up by him. And unfortunately she didn't know you'd be on your way.
