A Long time ago, a curse was cast upon the Rindo HouseHold. The curse: the HouseHold could only give birth to boys. The only way to temporarily lift the curse was to have a with someone from the Hizuki HouseHold. Once the curse was lifted, it would haunt the HouseHold again every 3rd generation. Many s have passed and now, Naoto Rindo will be the unfortunate one. His former fiancé from the Hizuki HouseHold has passed away due to a tragic accident and now he must impregnate one of the other four girls from the Hizuki HouseHold, however, time is running short.

Will he be able to successfully impregnate one of the girls with a boy? Or will the curse ruin his life, forever….
