Synopsis: A long time ago, a curse was cast upon the Rindo family: the family could only give birth to boys. The only way to temporarily lift the curse was to have a child with someone from the Hizuki family. Once the curse was lifted, it would haunt the family again every 3rd generation.

Many years have passed and now, Naoto Rindo is the unfortunate one. His former fiance from the Hizuki family has passed away due to a tragic accident and he must impregnate one of the other four girls from the Hizuki family; however, time is running short.

Will he be able to successfully impregnate one of the girls with a boy?
