My Baby is Actually My Ancestor!

Melissa was tricked into a pregnancy before marriage and then slandered for it. Her family expelled her and made her change her surname. She raised her daughter Margot on her own, the two of them depending on each other. The soul of the family's founding matriarch then entered Margot. The matriarch learned how her distant descendant was living. Margot, carrying the old woman's soul, led Melissa to Michael. A mix-up over who was related to whom put Melissa inside a wealthy household. From there Margot worked at bringing Melissa and Michael together, and used her own abilities to get Melissa through several crises connected to Michael.
