Regulus/Remus
Regulus didn't know what to expect or how this 'club' would be different from the one in the Room of Requirements. He was born in 1961, there were no clubs in wizarding Britain when he was growing up and besides, he'd been out of school for less than six months before he died. Six months taking care of the finances after his father had died and finding a good match. He hadn't had the time to find clubs all around the world, therefore this was new.
In the end, it wasn't so impressive. It looked nice enough, but it was always the same people. The music was loud and he didn't know what he was meant to do. There was some juice concoction. He heard someone call it Pimm’s punch. He didn't know what Pimm's was, but he could taste some mint leaves, cucumber, orange and strawberries. It was sweet and good and he kept going back for more.
"Hello I think-" He blinked when Remus got all fuzzy. It must have been the lighting, but he put an arm on Remus' shoulder so he'd stop moving. "The punch might be more than fruit juice," he finished, laughing. "It's very good."
