The Substitute Bride: Claiming the Black Dragon’s CrownEpisode 11

"Sacrificed as a useless pawn by her own royal blood, the princess Isolde strikes a deadly bargain: a life-binding pact with a dying Black Dragon Lord. Reborn with terrifying power, the Dragon Lord helps her shatter the hypocritical royal court—only to claim her as his prize, locking her away in his frozen Northern citadel. But Isolde, now carrying his dragon seed, refuses to be a caged pet. When the Holy Church’s army lays siege to the fortress, she doesn't cower. Instead, she hijacks the citadel’s core magic, completely flipping the script. She brings the dangerously possessive dragon to his knees in willing submission and births his ultimate heir. Leading a monstrous army to raze the royal capital to the ground, Isolde judges everyone who ever wronged her. Rising from a doomed sacrifice to the ruthless Queen of the continent, she transforms her former prison into her absolute throne."
