My Younger Brother Is a Super-Aggressive Monster

My mom is pregnant. It's the boy she's always dreamed of having.

But the results of the genetic screening are bad. My little brother has XYY syndrome, and everyone is urging my mom to terminate the pregnancy.

But my mom refuses to give up and insists on having him.

I ask Mom, "What's XYY?"

Mom tells me, "Your little brother is a super-strong young man. He'll protect his big sister."

I don't quite understand. But when my little brother is seven, he hits Mom on the head with a brick, again and again.

I think I understand what it means to be a young man.
