Abby is reborn into the body of a 5-year-old girl, only to realize she is the long-lost billionaire heiress who was switched at birth. In her previous timeline, she lived a miserable life, nearly beaten to death by her drunken adoptive father, while a mysterious 'System' nagged her to fulfill a tragic villainess role destined for death. This time, Abby has a different plan. Armed with her innocent looks and an adult's cunning, she decides to ignore the system's doomed mission. She steps out of the slums and walks straight up to her biological mother, the most powerful woman in the city, and simply says, 'Mommy, I'm your baby girl.' With a multi-billion dollar family backing her, she’s about to show the world that even a five-year-old can rule the empire. A unique rebirth tale.
