[ENG DUB] The Last Proof That Slayed Them All

Brilliant mathematician Aurora, whose equations once aided military research, is revealed as the long-lost daughter of the affluent Winslows. Brought into wealth, she faces scorn for her rural past and is eclipsed by Luna, the family's favored adopted daughter. Luna orchestrates repeated frame-ups; at a decisive exam she brazenly copies Aurora's answers, yet Aurora is blamed and punished. In her next life Aurora returns, steeled by a vow of revenge. When Luna provokes her again in the exam hall amid the family's obvious bias, Aurora publicly cuts ties with the Winslows. Calm but relentless, she refuses humiliation and begins to unmask the injustices, determined to reclaim her identity and expose those who betrayed her.
