Levi's overprotection can also shape the relationships in the plot. Other characters might view Levi's actions towards Eren in different ways. Some might support Levi, thinking Eren needs that protection, while others might side with Eren and encourage him to be more independent. This can lead to various sub - plots and further development of the overall story.
The theme of self - discovery for Eren is quite common. With Levi always hovering, Eren might initially feel stifled but then realizes that Levi's overprotection is a form of love. This realization helps Eren understand his own worth and his place in the world around him. And there could be the theme of redemption as well. If Eren has made mistakes, Levi's overprotection can be a way for Eren to redeem himself under Levi's watchful eye.
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.
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 aspect of Levi x Eren family fanfiction could be the exploration of their relationship in a family - like dynamic. It might involve how they support and protect each other within this new family structure. For example, Levi could be a strict but caring figure, while Eren is the one with new - found responsibilities in this family.
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.
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.
Female Eren in this fanfiction is often portrayed as headstrong. Just like her male counterpart, she has a strong sense of justice and is determined to fight for what she believes in. She is also likely to be brave, not afraid to face danger head - on, whether it's in battle or when confronting the complex relationship with Levi.
Levi sees Eren as a complex and unpredictable character. He recognizes Eren's potential but is also wary of his intense and sometimes uncontrollable nature.
I'm not sure specifically about this fanfic's plot without reading it. But generally in Eren x Levi fanfictions, it could involve themes of their relationship development. Maybe Eren has been away for some reason, and Levi is longing to see his face again. It might explore their complex feelings towards each other, whether it's friendship that's evolving into something more, or a pre - existing deep bond that has been strained and is now being mended.
Fanfiction about Eren and Levi kissing can be quite interesting. It might explore a different side of their relationship. Some fanfictions in this regard could be about a moment of emotional intensity between them, where the kiss represents a deep connection that goes beyond their usual interactions in the original story.
