The bar is kind of a bdsm one where the bar worker was a “queen” and the salaryman is kind of close to the bar owner and asked for the queen. They had sex but i forgot who was the top, the salaryman was a dominant bottom and the bar worker was a submissive top. The salaryman also confessed with a bouquet of flowers to the bar worker. Thats all i can remember
