Help me find this yaoi

I think I may be making it up and it doesn’t exist but I hope it does, at first I though it was master peace because that’s how I remembered the characters and the artstyle but I read it and it wasn’t the same. Basically there is buffer, in a suit, mafia boss kinda guy tho I’m not sure if he actually gang related or anything, and some other guy they both have dark hair. The smaller guy is super obsessed with the boss to the point that he begs him to hit him and the boss hates him, I think over time the boss begins to be worried about him and etc.
