Well, it really depends on the Christmas story. If it's a really sad one about someone being alone during Christmas or something tragic, then maybe. But generally, most Christmas stories are positive and full of hope, so I probably won't cry.
Fanfiction is a creative way to expand on existing fictional universes. 'it's gonna hurt fanfiction' could potentially be about a character's journey through a tough time. It might involve themes like heartbreak, betrayal, or the pain of growing up. For example, if it's a fanfiction based on a superhero story, the hero could be dealing with the pain of losing their powers or being ostracized by their former allies. The writer might be using this to explore deeper emotions and character development within the framework of the beloved original story.
One common theme could be adventure. Since the 'Twin Tail' series itself might have elements of action and adventure, fanfictions may expand on that. For example, the characters going on new quests or facing different threats.
