I do remember there was a similar story. Where the alpha rejects the “fated” omega to stay with their partner. I can’t remember the name but I do remember the omega actually following the alpha around and kept insisting that they should be together instead. I think the omega might have even went to meet the alpha’s partner. Ughh if anybody can remember please let me know or recommend similar stories.
