‎很久以前，林多氏族被复仇的灵魂诅咒，以至于没有男孩出生。为了对抗诅咒，每三代人，林多必须生一个拥有强大精神能量的家庭的孩子。从那天起，肥越家族就一直是林多的重要和善待的仆人。他们有责任每三代将他们的血统与林多继承人的血统混合在一起。‎

‎时间流逝，这种做法一直持续到今天。目前的继承人是直人，他的未婚妻铃根在一次事故中去世。现在，他需要找到一个替代者。‎

A long time ago, the Rindo Clan was cursed by a vengeful spirit so that no male children would ever be born. To counter the curse, every three generations, the Rindo must beget children with a family possessing strong spiritual energy. Ever since that day, the Higetsu family have been important and well-treated servants of the Rindo. It is their duty to mix their bloodlines every three generations with that of the Rindo heir.

Time passed and the practice continues to this day. The current heir is Naoto whose fiancee, Suzune, passed away in an accident. Now, he is required to find a replacement.

Naoto et Ayumi, tels un jeune couple modèle, vivent un parfait amour. Un jour, la jeune femme retrouve la bague de mariage de sa sœur et la montre à son chéri. Au moment où le jeune homme touche la bague, Ayumi perd brièvement conscience. A son réveil, l'âme de Suzu, l'ex future femme de Naoto disparue dans un accident de voiture, se retrouve dans le corps de sa remplaçante !
