Boku wo Sodatete! Nyanda Seijin

My husband divorced me because I couldn't have children.

One day, I found a strange egg.

I didn't know what kind of egg it was, but since I'd been wanting a pet, I decided to take it home and try raising it. Surely a cute little bird would hatch...

But to my surprise, what hatched from the egg was a tiny boy with cat ears!?

This child, who called himself a "Nyanderian", asked me to raise him for five days until he became an adult...
