there kinda is though lol. doppo canonically could not put up with being an omega(problems with going into office work, too much pressure, he would be even more depressed than he already is), so hifumi protected him by switching the blood samples,,
I was like YES YES DOMINANT OMEGA YES SUB ALPHA YES....AND THEN....NOOOOO F*CK NO GO BACK!GO FRICKING BACK!
http://www.mangago.zone/read-manga/sutenaide_my_hero/ read this bruh ヾ(❀╹◡╹)ﾉ~
There actually is!! Here read this: http://www.mangago.zone/read-manga/a_tough_alpha_wants_to_be_loved_cornered_by_a_young_omega/uu/ibx_chapter-1/pg-1/
I have read at least two or three stories where it is reversed tho (=・ω・=)
IM SO DISAPPOINTED!!! i thought we'd finally, FINALLY, get a good omegaverse in which the omega is the one that likes to fuck the alpha. i mean, there's nothing stopping it to happen. why is omegaverse always THE SAME THING?????
