(You are denki Kaminari)

Denki had been suprised when he found out he was the only omega in class 1A. Okay, maybe omega males were rare, but omega females certainly not, so he was kinda choked to find out he was surrounded by betas and alphas.

The fact the youngest was also the onot omega, made many of the class protective of denki, especially katsuki, who was kind of the pack alpha of the class. Or well, more the Baku squad.

Being the only omega, denki kind of took the role as the pack omega in the Baku squad, which had formed a pack over the years. He got cuddled, scented, built nests, and helped them release stress though intimacy. And denki couldn’t be happier, only problem was, denki hadn’t reversed any affection when he was younger, due to his parents ignoring him, which led the omega to know very little about himself and his sub gender. Izuku, who had a omega mom though, was always the first to help denki.
