Honestly I think they could make it work but they would have to actually communicate for that to even be a good option. But the ML prefers to hide his reasoning for some reason?????? Like it was absolutely dangerous for the ML to lie to his partner and sneak away while medically unwell. What if something DID happen as you say, what would the MC and child do? The MC has like zero support, would he just lose everything?
Maybe if they actually discussed their situation and goals, they could come up with a plan - considering heats and unstable medical conditions happen to omegas. But you're right to some extent, they could definitely encounter bad situations if they aren't planning for the future.
Perhaps if there is a 2nd volume they'll discuss it properly again. Im also very curious about the omega's reasoning of being afraid of changing after bonding. Ive never heard of an omega changing after bonding and also cant really imagine how that would look like. I feel like having a baby would change you a lot more than bonding

Alright, I wasn't a fan of the ending because they didn't actually discuss things properly themselves. Two other ppl intervened (one was an asshole about it) and the final discussion wasn't actually about both of their feelings. It was just MC (alpha) confessing again, and apologizing, while ML(omega) still didn't directly actually say what he felt and thought - "I want to have both a career and family life with you, I actually love you but I don't want to lose my independence." It was more like "I almost forced you into something you didn't want and I am sorry about that, my desires are merely biology, and I just want to stay besides you even if you're lying to me." It was just the MC groveling.
Then the audacity to not show an actual resolution with the other actor - just a "whoops, sorry teehee." But whatever, the baby is cute and I will root for MC (alpha) every time! If there is a 2nd volume, I hope they actually resolve that communication stuff. Because if I had to beg you to tell me you love me after everything we went through, I would not actually trust that we would stay together forever. But that's just me lol
