looking for bl (forgot name)

It was omegaverse, and the mc used to be a beta but randomly became an omega. He works at company as like a computer science guy and the ml is the director of the company. Mc doesnt like ml at first bc ml is weirdly rude to him but it was bc of a misunderstanding, i think ml thought mc got freaky at the workplace but idk if im remembering that right. After they clear that up, ml offers to help mc regulate his pheremones since mc doesn't know how (and he has a crush on mc) and they eventually fall in love and get together. Mc has brown hair and ml has black hair. The main conflict is theres some guy at the company who keeps spreading foul pheremones (?) and theyre trying to catch him bc hes targeting the mc. Some small things i remember is the mc's pheremones are like citrus flavored and he likes vitamin supplements and ginseng.
