Can't remember

Guys its a manga and it was omegaverse i think. I can't remember too much abt the main couple since they only had like 3 chapters but the side story is about the main couple's butlers. And its between an alpha and a beta. The beta had long hair but cut it later i think. And also the beta can't get pregnant because of childhood trauma or smth idkhelp me pls i want to reread it soo bad ╥﹏╥
