What are the common themes in 'Zero and Yuuki Vampire Knight fanfiction'?

In Vampire Knight Zero and Yuuki fanfiction, a common theme is the transformation of their relationship over time. Zero's struggle with his vampire nature and Yuuki's position in the vampire - human world add a lot of tension. Fanfic writers might create scenarios where Yuuki helps Zero come to terms with his darker side more effectively. They could also write about how their relationship might change if external threats were different. For instance, if the vampire - hunter conflicts were resolved earlier, how would that impact the way Zero and Yuuki interact with each other? It's these kinds of what - ifs that make fanfiction so engaging.

Another interesting plot twist could be a time - travel scenario. What if Yuuki was sent back in time to before Zero became a vampire? She could try to prevent his transformation, which would change the entire course of their relationship. This would also bring up questions about whether she should interfere with fate and how it would affect the future of the vampire - human world.
