beta
In my head, I would always want a omegaverse story where the omega/alpha had a misunderstanding, alpha blamed the omega for mating with him (even though he's the one who marked him), and in the end, the omega undergoes surgery to remove his mark to free the alpha. Then the omega survives, but the consequence of it is the omega never getting affected by pheromones and will be immune to bite marks (even if an alpha bit him, it will heal). He will be like an ordinary beta, but he will still have omega pheromones. The alpha will learn his mistakes and try to win over omega, but due to the mark removal, omega doesn't remember him. And even if they become a couple in the end, him unable to give the omega a permanent bite mark will haunt him forever.
This manwha touched on the bite mark removal surgery, but I really wish that the alpha will suffer once he realizes that he's the one who bites down the omega. It really pains me when the omega is blaming himself for his selfishness and really wished for him to escape that seme and just be with the childhood friend.
