One great Levi x Eren fluff fanfic is 'A Moment in Time'. It beautifully captures their relationship with soft moments of understanding and care. The author really focuses on their unspoken bond.
There's 'Gentle Encounters' which is filled with heart - warming scenes. It shows Levi and Eren sharing quiet times together, like having tea and just talking. The fluff in this fic is in the small, tender gestures they make towards each other.
In Levi x Eren fluff fanfics, their relationship is often painted with a lot of emotional depth. They are not just comrades, but something more. There are scenes where they look out for each other's well - being. For instance, when Eren is injured, Levi is the first one by his side, showing his concern not just as a captain but as someone who cares deeply for Eren. And Eren, in return, respects and admires Levi, and this is shown through his eagerness to learn from Levi and his small acts of kindness towards him.
It's hard to say. 'Levi x Eren' fanfics are quite common in certain fandoms, but the 'Levi is a criminal' aspect makes it a more specific and perhaps niche sub - genre. If there are a lot of fans who like to see dark or morally ambiguous takes on the characters, it could potentially be popular within that subset of the fandom. However, it also might not be mainstream popular as it goes against the more typical heroic portrayals of the characters.
One idea could be a story where Levi and Eren are on a dangerous mission together. They start off not getting along well due to their different personalities. Levi is strict and methodical while Eren is impulsive. But as the mission progresses, they gradually learn to understand and rely on each other. For example, Eren might save Levi from a Titan in a moment of quick thinking, and Levi in turn teaches Eren some crucial combat skills.
To develop their relationship realistically, let them communicate. Have them have conversations about their pasts, their goals. Eren might talk about his family and his drive to avenge them, and Levi could share some of his own traumas from his past. This would create a deeper understanding between them. Also, small acts of kindness like Levi patching up Eren's wounds after a fight or Eren getting Levi his favorite tea could strengthen their bond.
Maybe Levi is a criminal in the sense that he's part of an underground rebellion against an unjust regime. Eren, who is initially on the side of the establishment, meets Levi and gradually comes to understand his motives. Their relationship could develop as Eren has to decide whether to side with Levi or stay loyal to the regime, all while a romantic connection forms between them.
One common theme is the struggle with their different personalities. Eren is often impulsive while Levi is more reserved, and their relationship development around this contrast is a frequent theme.
There's also 'Eren's New Perspective'. In this fanfic, female Eren brings a fresh view to her relationship with Levi. It delves into how their different personalities clash and mesh. The story often has them facing challenges together and growing closer through shared experiences.
One positive theme could be their mentorship relationship. Levi could be shown guiding Eren in his growth as a fighter and as a person who is key to the survival of humanity in the 'Attack on Titan' world.
Sure. You can try looking on Archive of Our Own (AO3). There are many talented writers who create fanfics about Eren loving Levi. Just search for the relevant tags, and you'll find a wide variety of stories.
Another theme is redemption. Sometimes, Eren might be portrayed as having made mistakes and Levi is the one to guide him towards redemption. It shows the growth of Eren's character with Levi's help. This theme gives a lot of depth to their relationship.
