My Sister Stole My Fiancé, So I Stole the World (55 Eps)
Wealthy-family takeover line: Su Nian'an, heir of the Su Group, discovers at her engagement banquet that her fiancé Gu Yanxiu and her sister Su Nuanhe have been colluding, and that her grandmother wants her twenty-three percent stake moved to the sister. She tears up the contract on the spot, plays the terrace recording, then audits the books: forty million has gone to her sister's private account since her father died, signed off by vice president Zhao Hongyuan. She counters with her mother's original capital agreement, publishes the audit at the Yunqi Villa family meeting, forces the Gu family to show its hand, and takes the chairman's seat.
