The main characters in 'Vinyl Cafe Christmas Story' are probably the owner of the Vinyl Cafe and the regular customers. The owner would play a crucial role in creating the Christmas atmosphere and running the place during the holiday season. The regular customers would bring their own stories and personalities, perhaps sharing their Christmas plans or reminiscing about past Christmases in the cafe.
I'm not entirely sure as there could be multiple characters, but likely there are the regulars at the Vinyl Cafe.
Well, without having specific knowledge of every 'Vinyl Cafe Christmas Story', we can assume that there would be some common characters.
