Im pretty sure it is Anti alpha
never mind i don't think that's the one but it seems very similar
It was about a guy who was an alpha his whole life but he finds out he's an omega in an alpha school. He ends up with his very aggressive best friend. Erm I think he was lying about being an alpha because he came from a family of only alphas. The omega has white hair and the love interest has black hair. I forget the name. (〜￣△￣)〜
