have you tried scrolling thru the secretary or alpha x beta tags
Kinda fits the description?
Alpha x beta
Beta butler/servant, gets mistreated
Story is ass

This isn't omegaverse but sounds very similar:
Speak Of The Devil

ive alr posted this here before but no one seems to know what manhwa im talking abt,, im starting to think that this manwha doesn't actually exist
bl manwha where the mc is a beta and the ml is an alpha. they sleep w each other but they're not rlly lovers. theyre fuck buddies basically. the mc is the ml's secretary and he's kind of a pushover, still sleeping with the ml even after ml mistreats him. the art was good but the story's kinda ass.
