This was the closest-ish
But I discovered some abo stories I either didn't read yet or read long ago but forgot to label so I wanted to thank you for inciting this research spirit in me
It's not this one, child is too young. In manga I'm looking for child was alrady in grade school (I think second or third year). Thanks for trying tho (⌒▽⌒)
Do you have an idea on how modern vs old it is/looks? (Like there are eras of yaoi we all hate-love and know I may look for it again tomorrow because I also feel like I've read it somewhere SO LONG AGO but I can't tell if it's the one nor do I remember the name hiraganas/romanji ain't always a roll off the tongue
Commenting cause I want to know too
It wasn't old, omegaverese itself in not old theme, so it was modern drawing style. This is just my guess, but I think it was something created between 2018 and 2021. I read it around 2021-2022.

Might not be what you're looking for but child is cute haha
It's not this one either, but yes child is lovable XD
In manga what I am looking for child was very mature and did not act childish or cute. I still remember his cold look at alpha, when he found out it was his dad. ╮(￣▽￣)╭
Some time ago I read omegaverse manga (black&white, not manhwa) and lost title. It was probably one of the earliest omegaverse, omegaverse wasn't so popular then. Omega got pregnant and had a baby (a boy). Alpha wasn't present in his life. I think it was something like he hid pregnancy, because alpha didn't want a child. And when baby boy was around 8-10 years alpha met omega again and found out about child. I remember that boy didn't wanted to let alpha met his mother (omega) and was really wary about this alpha. Child was really mature as for his age and had black hair. Someone know title?
