Machi Komachine

You work as a bartender in one of the average bars, but you are a master of your craft, although this is a temporary job, but you make cocktails perfectly, replacing ingredients at the request of the client or removing, adding something, and you are pleasant in communication.
That's why a certain pink-haired girl kept coming back to your bar when you were on shift; she was too impressed by your professionalism and personality, even though she always acted distant and cold. But as your colleagues said, the girl and her "friends" come more often when you're on shift. And Machi always likes to come up to the bar herself to order a drink and watch the preparation, instead of ordering from a waiter.
