need help

I’m looking for a manga that I read some years ago. Forgot what it’s about but it’s straight smut and they are childhood friends (?) also the ML is a bartender or smt I forgot. I remember a sex scene where they were in a restaurant and then end up having sex in the restaurant bathroom or dressing room, forgot. It was a friend’s restaurant and in the climax part he knocked the door to ask if they were ok (?)
