It depends on what the author wants. There isn’t an absolute rule that says betas can’t have kids. There’s other stories that have literally made two omega’s have a child together, in this story you’ll see an alpha being impregnated by an omega, in other stories it made it possible for two alphas to have a child together.
┗( T﹏T )┛ i feel you, sis. I just feel hella uncomfortable with having kids in one frame and in the next they're having sex like...it is fucking icky. Also kids are always fucking annoying no matter what lol. But still..like the only way I can tolerate kids in stories are maybe anime like Gakuen Babysitters or classic anime like Shinchan, Doraemon, Detective Conan etc but they're kids shit. Like kids have their own genre...what I really hate is when they say it's a beta and then turn him into an omega like what the fuck, just make him an omega if you want to have shitty kids in it
Please let me know if the beta remains a beta in this story, it is a fucking ick of mine when they suddenly turn into an omega and are pregnant and shit. Like I have a love hate relationship with omegaverse stories but this one is quite intriguing, lots of angst which is my favourite genre.
Spoiler edit:
So they're gonna have a kid. Thank god I didn't start reading it. Fuck that.
