It's about a playboy who one day found a baby... and apparently, he's the father.

From Sugar-Oasis:
"I wish I was born in a normal family..." A high school girl, Sakamoto Kina, is one of the nine children in her family. She's so embarrassed that she can't tell people that she has such a big family. Of course, she can't tell Noguchi-kun, her crush, either... One day, Kina's mom, who is usually energetic, suddenly collapses...!!

Asami, a college junior, held out her umbrella to her lecturer, Mayama, two months before graduation on a rainy day. Although it was their first contact, Asami continued watching Mayama for two years.

Ami is a high school girl who loves to chase after expensive brands. By pure chance, Ami has started working for Tatara in order to acquire a handbag she wanted. But to think that Tatara is the most famous porno writer at the time..! Who could have imagined the anxiety that lies within Ami's heart?
