Haha I know
I'm not sure, but I think the omega doesn't say anything to his family, or if they know he is trying to show he's happy
But he suffers a lot
It's kind of blurry, but I think that the alpha bit him on the first chapter
I remember it went really fast

This one is good as Well, but I'm sorry it's not what I'm looking for
The alpha is really cruel with the omega, he only think a about his own desires

since i dont usually read omegaverse either i dont know but this list of this user may help: http://www.mangago.zone/home/mangalist/164842/ ╮( ̄▽ ̄)╭

Alpha does force omega to make a pair. But its only 2 chapters long and therr is a bit of bdsm... Idk think this is the one tho.
Hello
I usually don't like this type of yaoi, but I'm looking for an omegaverse. The alpha bites the omega without his contentment, and force him to be with him. I think he also forces him to be pregnant
