Maybe. If they are writers or filmmakers, they could be in the process of making a love story. But it could also be that they are just living their normal lives and there's no such thing going on.
No, I don't think so. Usually, if there was a new Christmas story being made, there would be some buzz in the media or among the fans. I haven't seen or heard anything about it. Also, making a new Christmas story requires a lot of resources and creativity. It's not something that just happens without any prior indication. So, in my opinion, they are not making a new Christmas story at the moment.
There's a chance they are. Christmas is a very popular theme, and there's always a demand for new stories. However, it's also possible that they are focusing on remaking old Christmas classics instead of creating a brand - new story. Without more information, it's difficult to tell.
One important aspect of making a short story is the characters. Develop them quickly but effectively. Give them distinct personalities. You can do this by their actions and words. For example, a character who always bites their nails when they're nervous. Also, start the story in the middle of the action. This grabs the reader's attention right away. And use dialogue sparingly but make it impactful to move the story forward.
First, create unique and interesting characters. They can be wizards, elves, or brave knights. Second, build a vivid and magical world, like a floating island or a forest full of talking animals. Third, think of an exciting plot, perhaps a quest to save the world from an evil dragon.
