Vera, the family's adopted daughter, was long drugged and exploited by her hypocritical best friend, who stole her life essence, reducing her to a "good-for-nothing" in others' eyes. After unexpectedly forming a blood pact with the aloof Duke Fan En, she discovers she is the sacred blood heir—a half-human, half-witch. Confronted with the family head Ignis's millennia-old conspiracy and cruel manipulation, Vera refuses to be a sacrificial pawn. Under Fan En's protection, she breaks free from mental shackles, awakens her purifying power, and exposes the false truths. From humble endurance to self-reliance, Vera and Fan En overcome class prejudices, achieve mutual redemption, and jointly safeguard the academy's peace and justice.
