"His Omega."

All Killua wanted was to be free, away from his family's grasps, and on top of all that, being an Omega didn't help. His brother had ingrained in his brain that Alphas were selfish beings. Only wanting sex, and getting an Omega pregnant.
What happens when Killua meets an Alpha? But weirdly enough, said Alpha isn't like anything his brother told him. In Killuas eyes, all he sees is a amber-eyed goofball that drinks wayyyy too much coffee, and that's alright. He's his Omega after all, and he's not going anywhere.
