Lady Symphania Ice Crystal, the beautiful daughter of the Marquis, was cursed by the Second Prince, who possessed witch's blood, and transformed into a woman in her childhood.

The curse remained unbroken as long as the Second Prince harbored an obsession for Symphania, and ten years passed since she reluctantly became his fiancée.

Things began to move when the Second Prince annulled his engagement to Symphania.

Upon the curse on Symphania being lifted, he reverted to his original male form, reclaimed the name Sifas, and led the Marquisate family in a civil war against the kingdom.
