A queen relives her childbirth night, catching a maid trying to swap the babies—and secretly swaps them back. For eighteen years, the foolish maid cruelly abuses her own resin-bodied daughter, believing she is raising royal blood. When all lies collapse at the sacred blood pool, the true princess refuses to harvest innocent marrow to repair her decaying golden tooth. Instead, she destroys the cannibal ancestral altar, abolishes the tooth-based caste system, and brings equality to every citizen of the kingdom.
