Are you talking about this one?
Although similar, it’s not an omegaverse, it’s another concept that has been recently started and I’m not sure how they officially call it. Dom x Sub.

Not all of them are rape if we're going to be honest. Some of them definitely romanticize rape but there are more wholesome ones. There's adorable family versions like this: https://www.mangago.zone/read-manga/tadaima_okaeri/
There’s another one from the same universe here, but it’s not complete yet: https://www.mangago.zone/read-manga/collar_kiss/
I hate it when it is romanticized but yeah the wholesome ones are really great! I like this one https://www.mangago.zone/read-manga/kiraide_isasete/
bestie, things are situational. There are things people say that you need to take with a grain of salt. They apply to certain situations and not others. I understand your aversion because you've probably only found some really shitty things. However, based not the examples others were giving, you should have understood that we weren't looking for rape content. Also, this omega verse was closer to toyless BDSM than rape as far as I can remember.
I got into abo before it really became a Korean or Japanese comic thing. For me it’s because I encountered books or fanfics that really delved into the speculative fiction that it is. When it came to the fics, especially ones that it was alien races that had the A/B/O dynamics, it was exciting to see how the author played with the concept. Some stories didn’t have heats, some the alphas deposited the eggs betas fertilize them & omegas incubate them, some have gammas & deltas, I’ve read one where omegas primarily are born into this religious group (the author mixed elements of jewdiasm & Amish+Mennonite), some are just general stories... There is so much you could do with, and the possibilities expand once you add other forms of speculative fiction or tropes.
So basically it’s omegaverse im pretty sure but in the story the omega is pretty destructive and gets in fights a lot but the school makes him roommates with someone else (the alpha) and the alpha gives him commands and the guy does them even if he is unaware of it and eventually he gives him a collar. Also a weirdly specific thing I remember was that the nurse also had a collar and showed the omega that. But yeah. I need help because I remember it being really good ;;
