Shinomiya Shuka, the youngest child of a wealthy conglomerate family.
Talented in both brains and brawn, with wealth and good looks to boot!
One day, at the school gate, Shinomiya Shuka discovers something incredibly bizarre.
A girl named Furukawa Nagisa claims to be his daughter, from the future, and says her mother is his childhood friend, Furukawa Sanae.
In the future, his marriage falls apart because he falls for his junior, Touma Yoko, so Nagisa has come back to give him a little push, even if it means sacrificing herself.
After that, Yukinoshita Yukino shows up, then Touma Kazusa, then Katsura Kotonoha, along with a whole bunch of other daughters. They all claim he's their father.
But he, Shinomiya Shuka, just wants to study. He doesn't want romance, and he certainly doesn't want to be a father!
Until one day, he personally drives his own family business into bankruptcy.
