What are you talking about? This is totally leading up to that.More than any other mangas I have read. I personally think it will be interesting to see the dynamics between all three of them.In all of the A/B/O mangas we have read, its always either the fated mating, or defying the odds and choosing a beta mate. Here, we have a chance to see how all three of them work together as a unit.
This story is not leading to that.
It is either accepting destiny or fighting it and choosing your own fate. As if that alpha asshole will accept to share. And if the omega is bitten by his alpha, it'll be difficult for him to be with another person. So I think you're wrong. We will have to wait and see.
this better be a threesome(☆▽☆)
