Well, not so sure how to explain about it but, this manga, the first pages (well starts on pg 6) it explains basically everything of it, also it's a good omegaverse as well :> http://www.mangago.zone/read-manga/abarenbo_honey/
I think basically all omegaverse manga have the "rules" printed right before the story and it explains it all! I'm not very fond of omegaverse (a lottttt of them have rape and prejudice) but my favorite one is Sayonara Alpha...it's really cute
Tadaima Okaeri is the fluffiest cutest one out there thought ε=ε=(ノ≧∇≦)ノ
Oh yea that one gave me diabetes. This one's a great starter one too http://www.mangago.zone/read-manga/kashikomarimashita_destiny/
I have been seeing these types of stories pop up more and more, can anyone explain to me what an omegaverse is and recommend any good starter ones to read? ╥﹏╥
