Help me find the bl manga

Ok I'M BAD AT EXPLANATION. Here's what i remembered: it's office romance. Black hair dominant, light hair submissive. The black hair is kinda a people pleaser. And there's like the light hair guy bestie that's also gay and in a situationship with a bartender. The bartender has a long hair and mustache and beard. That is all. Hopefully someone will answer. Thanks in advance
