I recommend checking these out for some variety. Mangas that don’t start with omegas experiencing heat and the alpha fucks them:
http://www.mangago.zone/read-manga/okusama_ha_alpha/ (alpha/alpha, arranged marriage)
https://myreadingmanga.info/asou-mitsuaki-rebirth-eng/ (alpha/beta faking being omega, mystery and crime on the side)
http://www.mangago.zone/read-manga/sensei_no_sensei/ (alpha/beta, best slice of life with omegaverse world-building)
http://www.mangago.zone/read-manga/kimi_wa_mu_kamenai/ (beta/omega omega experiencing heat but a beta fucks him tho it’s a job lolll)
Wow bless you
At the start uke was kinda rude to his coworkers so it makes sense that the seme thinks his a prick but at least the seme didn't try to like blackmailing him and honestly that counts for something cause all omegaverse stories are like the same thing with minor differences.
