I Found A Family That Wasn’t In My Adoption Plan

She was the most competent secretary of the Brauno family, the most prestigious in the empire, but one day, she was betrayed and killed by a hitman! Was it because of the resentment she faced for not being a noble? Or because of her desire to become one? She reincarnated as Aerin, the seven-year-old illegitimate granddaughter of the Brauno family!! However, even as this child, shes destined to be adopted and killed by the same man who betrayed her in her previous life. No way! Before I die by his hands, Ill get adopted by someone else! Huh? All I wanted was to be adopted, but now Wealth, honor, and even a new family that wasnt part of the adoption plan come as a package deal. Aerin! Take me! No, I already have too much. Its fine if you just add me to your endless list of assets. But how could I possibly take in a prince? At this point, should I just take over not only the family but the entire empire too?
