Tbh, I'm glad the author stuck with letting the mc remain a bets. Because there's already many stories out there that has beta turned omega.
And also, I find it weird how folks often expect that main characters in abo will have kids even if theyre a beta. Like it's almost a given that they'll have one. I know it's due to the nature of omegaverse but can't we just be content that they have their happy ending with or without kids?
Well that is you and this is me
Happ they dont have kids. Omegaverse aside, they are 2 men. Not a man and a woman. Not 2 men to be fetishized through heteronormative lens. Omegaverse by default is a giant fetish anyways albeit a weird one that gay people find ick. Besides they make it quite clear that they're not the type to have kids. Joo-in is a giant baby himself, and Prince would never let any other priority interfere.
It’s already a side story it would be nice if he become omega an have kids with the prince hmm…but still nice ending
