I don't think so..
But first let me explain, i've read an omegaverse manga like this too, but after the mating (between alpha and omega), not long after the intercourse the omega regretted and have sex with his love (a beta) until he get pregnant.
But in utou case, after the mating happened they didn't have sex, and determined enough to replace "the alpha" inside utou, and this is why... I still have bad feelings and there is possibility that they cannot be together.
╥﹏╥
But there's always miracle ヾ(❀╹◡╹)ﾉ~
I mean... Replace "the alpha" inside sasabe sorryy
From what I read in another manga, the bond would only disappear if the alfa die. But unfortunately, it does not seem like it's going to be the case.
Actually I read in another omegaverse story, that when a bitten omega loses it's alpha (death) it does NOT become a free omega again, they are stuck with that mark forever and ever until they also pass onto the after life. I think omegaverse is surposed to be romantic in a way
