Izuku: Omega, Katsuki: Alpha

—

Katzuki Midoriya-Bakugo was six years old, and life couldn’t have been better. He was the only child of Izuku Midoriya and Katsuki Bakugo, and his world revolved around them. Spoiled rotten, Katzuki was used to being the center of attention. Izuku and Katsuki would pick him up early from school just to spend the day with him, taking him out for ice cream or playing games for hours. Everything was perfect.

That was until one day, Katzuki’s parents made an announcement that shook his entire world. They were having a baby. At first, Katzuki didn’t mind. A baby sibling seemed fine. Babies were small, couldn’t do much, and would be easy to ignore, right?

But as time went on, Katzuki began to realize that things were changing. His father, Izuku, became more tired, and his once-constant presence started slipping away. Katsuki, ever the protective Alpha, spent more time taking care of Izuku. And Katzuki felt it—he wasn’t the main focus anymore.

The weeks leading up to the birth were filled with jealousy. His parents, once his everything, were now too busy with the baby. Even the stories of the Final War—a battle that had left both his parents scarred, inside and out—didn’t seem to comfort him. His parents had fought, bled, and sacrificed for their world, but now their attention was divided.

It all came to a head one night when Katzuki exploded.

“Why do we even need another baby?! You already have me!”

Izuku pulled him into his arms, his tired yet warm scent filling the air.

“You’ll always be our baby, Katsu,”

He whispered. Katsuki ruffled his hair with a grin,

“Like we’d ever stop spoiling you, brat.”

Katzuki didn’t like the idea of sharing his parents and he wasn’t going to make it easy on his new sibling.

That was for sure.
