It could be that there was some sort of misunderstanding between Eren and Levi that led to them being apart. Eren might have left in anger or confusion, and Levi regrets not being able to stop him. Now, Levi is searching for Eren, not just to see his face again, but also to clear up the misunderstanding. The fanfic could explore their emotional turmoil, the memories they have of each other, and how they will react when they finally meet again.
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.
Well, sometimes Tumblr can be a good place to find fanfictions as well. There are many fanfic writers who post snippets or links to their full works there. Just search for the title 'To See Your Face Again' along with 'Eren x Levi'. However, Tumblr's search can be a bit tricky, so you might need to dig a little deeper. Also, keep in mind that the quality and completeness of the fanfics can vary.
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.
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.
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.
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.
One interesting plot idea could be that female Eren, with her strong - willed nature, challenges Levi's authority in the military. This creates a tense dynamic as they initially butt heads but gradually come to respect and even develop feelings for each other. Another idea might be that they are on a secret mission together, relying on each other's unique skills to survive and in the process, their relationship deepens.
Character growth is also important. As they interact, both Levi and older Eren usually experience changes in their beliefs and personalities. For example, Levi might become more open - minded, and older Eren could become more understanding of Levi's strict ways. Another element is the setting. Whether it's in the familiar Attack on Titan world or a re - imagined one, the setting can greatly influence their relationship and the plot. If they are in a war - torn area, they may rely on each other more for survival.
A common theme is the idea of found family. Levi and Eren, who may not be related by blood, come together to form a family unit. This often involves themes of loyalty and trust.
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.
