She lived an ordinary life and died young. She didn't want to be a person again, but apparently Heaven hadn't heard her plea. She became a wandering soul, though the world she found herself in didn't seem to be her own. Later, she discovered it was the world of a novel.

Fortunately, she met a powerful benefactor and clung tightly to him.
