Pardon me, i din't understand what you said. Could you explain me?

well, for one this type of AU(alternate universe) is characterized with submissive character going into heat, differentiated male biology, fights for dominance, etc. With Yaoi being Yaoi.. ain't those just perfect???!!!!! It leaves a room for artistic twists and plots..

They just want to make babiesლ(´ڡ`ლ)

It been getting a bit of a mini revival in English, it seems, cos there are a lot of yaoi-readers out there who don't even know that it exists. I think there's also particular scanalation groups looking to translate omegeverse manga specifically.
I have seen a lot of these omega and alpha stuff but that the hell is it! I mean it's cool but..... Why is it everywhere as of late?
