Suzune is known as a “cursed child”, said to mislead even the kindest of people. Several years ago, a once-gentle neighborhood priest went into a frenzy at the sight of her blood, leaving Suzune with a deep wound on her back. From that day forward, she was branded with the stigma of being “cursed.” Burdened with debt, her family chose to sell Suzune—not her twin sister—to a pleasure district island. There, she works as a maid, forced to wear a mask to suppress her "curse," and endures daily mistreatment... One day, Yakumo, the head of a powerful conglomerate who controls the sea around the island, visits. Rumors say that “any courtesan chosen by Yakumo has no memory of sharing his bed.” Drawn in by Suzune’s unique “scent”, Yakumo demands to take in the girl who was abandoned by her family… Thus begins a Japanese-style Cinderella love story, born from a marriage to a vampire!
