Incorporate other minor characters from the historical context. They can interact with Helen and Amon Goeth, add more layers to the story, and provide different perspectives. For instance, other prisoners who might envy or pity Helen for her relationship with Goeth, or other Nazi officers who could influence Goeth's actions towards Helen.
Create internal conflicts for the characters. Helen could struggle with her will to survive and her moral compass in the face of Amon Goeth's actions. Amon Goeth could have an internal conflict between his loyalty to the Nazi regime and his growing, unexpected feelings for Helen.
A common theme in such fanfiction could be survival. Helen Hirsch had to endure the horror of the concentration camp under Amon Goeth's watch. Fanfiction might show how she used her wits and strength to survive in this harrowing situation.
One idea could be a 'what if' scenario. What if Helen managed to escape on her own and Amon Goeth had to hunt her down not as a prisoner but as a fugitive. This would change the power dynamic between them.
In fanfiction, the relationship between Amon Goeth and Helen Hirsch can be explored in various ways. Some fanfictions might focus on the power dynamic between them. Given Goeth's position of power in the historical context and Hirsch's victimized state, it could be a dark and complex exploration.
Add some mystery. For example, there could be a strange occurrence in the dalmatians' neighborhood like missing pet toys. The dalmatians could then set out to solve the mystery.
There might be a fanfic that focuses on the relationship between Amon Goeth and a particular Jewish character in the camp. Ralph Fiennes' Goeth could be written in a way that shows a strange kind of respect or even a budding friendship (although a very complex and conflicted one) with this character. This would add a whole new dimension to the story and his character.
A fanfic could explore an alternate universe where Amon Goeth and Oskar Schindler have a different kind of relationship. Ralph Fiennes' Goeth might start to question his loyalty to the Nazi regime because of Schindler's influence. This could lead to a series of events where Goeth has to make choices that put him at odds with his superiors, all while his character is explored more fully through the prism of a fan - created narrative.
You can focus on their emotions. Show their deep love, but also their doubts and fears. For instance, Guinevere might worry about the responsibilities of being the queen and how it will affect her relationship with Arthur.
To make it more engaging, use vivid descriptions of Jungkook's emotions. When he is in pain, really make the reader feel it, and when he starts to heal, show the small joys. Another way is to include some plot twists. Suppose he thinks he has found a solution to his problems, but then something unexpected happens that throws him back a bit. And don't forget to use dialogue effectively to show his character's growth and thoughts.
Give them unique traits related to the game. For instance, if it's a game about magical creatures, a character could have an uncanny ability to understand the creatures' languages. This would make them stand out and add depth to their role in the fanfic.
Another idea is to give Bob some sort of quest. Maybe he has to find a lost book that holds the key to saving the world of literature. Along the way, he meets various characters and overcomes different obstacles, which would keep the readers hooked as they follow Bob's journey.
