For the first few chapters the main alpha is so f*cking confusing. He talks about how alphas and omegas are human first designation second, yet still hates omegas because his omega dad slept around to earn money, had two kids with unknown fathers and refused to settle down with one partner. Then there's something about an omega pairing with an alpha to stop the nature of an omega to seek sexual relief in any and all willing bodies, yet he respects his omega boss who is somehow both very competent yet uses his omega body as a tool to get to the top and is prideful in his looseness, something alpha seems to be against? Like dude, what do you want? Do you hate omegas, do you pity them, do you just hate your alpha self, which is it? Stop contradicting yourself, it's confusing.
Edit: It's fear, with a smidge of pity. He does the classic thing where he's the only alpha around to be able to stop himself from sex when confronted with his boss in heat because he doesn't want to sleep with his boss and by extension be like the alpha's that used his dad. He hates the idea of being an alpha like that, he's scared of it even. He admires his boss for using alpha's dicks against themselves and conning them into doing as he wants. After The Shitty ExTM shows up, they start to realize they like each other, alpha says he wants to be a good alpha towards his chosen omega and omega wants to pair up with him after all. Basically, the whole "it's okay if it's you/you're special" routine, which is a trope and a half but still somehow cute. Probably a trope for that reason.
