1) Fargo already made it clear that betas cannot get pregnant.
2) Dojun clearly said he never wanted to have a kid. Heesoo supported that decision when he gave Dojun a second chance, and lived together with him.
3) They ARE happy as it is. Dojun may not have a lot of facial expressions, but he does look happy to me.
4) Babies are not the only purpose of being in a relationship. And not everyone needs, or wants one. You don’t need a baby to be happy.
1) Yes you are right. But it's still not impossible that Heesoo is not a full Beta. Remember in the beginning when Hyesung thought he was an alpha all his life? Turned out he was not lol.
2) Yes he did, but decisions like that can change over time. Also only because being with Dojun was more important to Heesoo at that point still doesn't mean the urge to have a baby just disappears completely.
3) They may be happy, but that doesn't mean they could be even happier.
4) Of course they are not and I didn't mean to say they can only be happy if they had a baby. But it is obvious (at least for me) that Heesoo loves children by the way he interacts with Byul. And if Dojun is imagining a happy life together with the both them, could mean he has a wish to have a child deep down inside of him too.
So let's just see what happens. Maybe that's even what makes their story so interesting, not knowing if they could have a child if they wanted to. :)
Heesoo said that it wouldn't calm Dojun down if he had Sex with him, because he was not an Omega. But in the end it did calm him down. So do you think it's possible that Heesoo is half Omega or something and just didn't know? Maybe that also means he can have a kid after all. Please I just want them to end up happy, they deserve it so much ┗( T﹏T )┛
