Fake Heiress, True Queen FHTQ

“Catherine is the sole heiress to a wealthy family. She grew up surrounded by luxurious food, fine clothes, and was surrounded by servants.
However, things took a turn she never expected – she was not her parents' biological daughter. The real daughter of the Kate family has now returned.
20 years ago, at the hospital where she was born, the nurse mistook her for another child. She was just the daughter of an ordinary family.
"Catherine, you don't have to call me Grandpa anymore," her once amiable grandfather said calmly.
"I propose to kick Catherine out of the family. She is only an outsider and has no right to inherit the family property," Catherine's uncle said coldly.
“I’m sorry, Catherine. We owe Millie too much. We made her suffer so much. Now we have to give her more love.”
Her parents said something apologetic, but they never looked at Catherine while saying it. Their eyes stayed on Millie the whole time.
Catherine smiled. "There's no need to apologize. I should be the one apologizing. As an outsider, I allowed the Kate family to raise me for so many years without any compensation. I'll return what I owe you. Goodbye."
Catherine turned and walked out of the Kate household without looking back.
Her family banished her, and her former siblings refused to talk to her because she was not the true heiress, but what did it matter?
"Boss, I heard that the Kate Family kicked you out of the house! They're asking for it. Should we send someone to ruin the Kate Family?” The leader of the Coven said.
"Chairman, as long as you agree, I will bankrupt the Kate family within a month," one of the heads of the world's top financial groups called.
"Lady Catherine, do we need to impose legal sanctions on the Kate family?" An official who was in charge of the Kate family's black market asked coldly.
She might be a fake heiress, but she was a true queen.
