Osanai Jibun wo Sodateru Koto ni Narimashita

Orphaned by a carriage accident, Zoia is raised by relatives who blame her for her parents' deaths, strip away her inheritance, and reduce a noble daughter to a servant in the house that should have been hers. Alone and worn down by years of cruelty, she takes her own life, only to wake ten years earlier on the day of the funeral, standing beside a weeping child who is unmistakably herself. Tempted for a moment to end the girl's future before it starts, she chooses instead to become the rescuer nobody ever sent for her.
