Rise of the Hidden Heiress(English-dubbed)

Valerie looks like a nobody, but she's the secret daughter of crime lord Arthur Morgan. To save her mother, she's thrown into the underworld, a pawn in a deadly game. But she survives. Feeding intel to the police, she orchestrates a bloody trap, watching the syndicate destroy itself. When the smoke clears, she walks away from the bloodshed, aces her exams, and rewrites her destiny.
