honestly i think it's more just a barrier/self defense mech he has put up for himself. he is in love with another alpha but since he believes he can't be with him, he needs a firm excuse for not pursuing it and protecting his own feelings, which is that they are both alphas. so if he can easily accept another alpha's feelings, then what was the point of not making a move on his bff all this time yk lol.
I have a different theory. Like maybe MC doesn't date alphas bc he's scared that any alpha he dates will leave him for an omega.
What you guys commented here are all because of internalised homophobia Omegaverse version.
Now that you said. It makes sense XD
Is this what you call internalised homophobia in Omegaverse? Your crush is literally an alpha but you're rejecting someone just because he's an alpha? Gtfo.
