Synopsis：In the Frostmark Empire, where winter never ends, only a marriage between a princess of true royal blood and the Abyss Dragon can restore the sun’s warmth. Princess Diana lived happily with her three brothers—until Lorelei appeared. Wielding a stolen dragon scale, Lorelei stole Diana’s love and status. Deceived, the brothers cast Diana aside, even offering her as a sacrificial pawn to slay the dragon. Only after the dragon carried Diana away did the truth come to light—but by then, it was already too late.
