Childcare

I lived suffering without a home, religion, or parents, but an angel appeared and reincarnated me. "You, a pro when it comes to romance fantasy novels, would you like to reincarnate in a world that was created based off of a romance fantasy novel?" I reincarnated because he said I would have a (handsome) dad and a (handsome) older brother who would spoon feed me, and even gift me a diamond mine, but... -I might be a child from my mother's affair? As soon as I was born, I was sent to my mother's household and fell into a family that deprives me. "If I stay like this, I might end up freezing or starving to death by myself!"

An orphan in real life one day wakes up as a main character in a novel she was reading. An orphan in the novel as well, she is adopted to a villainous family who served as the main adversary against the main character in the original plot... except, the family seems way nicer than she expected. Are these really the same villains that caused so much pain the novel?
