I own nothing but Adaliah. Feel free to read this as an X reader! I personally just prefer writing about an oc for simplicity and continuity. Thanks for understanding! Again though, feel free to read this as an X reader!

"Well then open it and get an idea!" The ash blond snapped, watching the white-ette roll her eyes.
Ever since that day at the park, the two kids have been inseparable. Adaliah's calm and cold precision always shooting down Katsuki's loud and fiery temper tantrums. They shared everything with each other, Adaliah even introducing him to her brother.
Kai, said brother, was a tall, intimidating alpha, who was three years older than they were. His hair was a dark chestnut brown, which was a great contrast to Adaliah's white hair, and if it weren't for their eyes, it would be questioned if they were siblings at all. Both had striking yellow eyes that would follow you everywhere, freezing you to place if they narrowed; Katsuki questioned if they were a second quirk. Kai was dangerously protective of his sister, so when Katsuki met him he was immediately thrown into the gauntlet with trying to prove himself worthy to even be close to Adaliah. Katsuki, of course took the challenge, proving himself in the seven years they had been friends.
The two never went to the same middle school, the girl going to a private school with Kai while Katsuki went to an unnameable, cliche public one. They never lost contact thought, hanging out after Katsuki was done (his classes went longer than hers) or over weekends, keeping their friendship as strong as ever. As they grew, he found himself much more protective over the omega, wanting to keep her close with a watchful eye- she was the first person he ever really considered a friend. His equal.
He wanted to keep her as safe as possible from the outside world, from villains. He would become a hero, and if he played his cards right, she could be his pretty, little, stay-at- home Omega. Who was he kidding? She would be his little, stay-at-home Omega. Oh, he lost count of how many times he's caught himself daydreaming about little hims and hers running around, Adaliah taking the role of mommy oh-so-well. Her cute eyebrows furrowing as she would scold their children.
The thought kept him up at night, feeding delusions and terrible intentions into his mind. Driving him further and further into his crazed mindset. Especially now that both of them were at the ripe age of fifteen, their inner alpha and omega respectively now looking for future mate candidates.
