I'm not entirely sure specifically about '50 shades of ereri fanfic' as it could vary greatly. 'EreRi' might refer to a pairing in a particular fandom. It could potentially be a fan - created story that takes inspiration from the '50 Shades' style in terms of exploring relationships, but with characters from the relevant 'EreRi' universe.
One interesting aspect could be the exploration of the relationship between the 'ereri' characters. If it follows the '50 Shades' inspiration, there might be a deep dive into their emotional connection and how it develops over time.
One interesting aspect could be the exploration of unique character dynamics. In ereri fanfiction, the relationship between the characters can be developed in ways that are different from the original source material. It might also show different interpretations of the characters' personalities. For example, how they interact in various situations, like facing challenges together or having deep emotional conversations.
One common theme is redemption. Eren might travel back in time to right his past wrongs. For example, he could try to prevent certain battles or tragedies that he feels responsible for.
Some fans are devastated. Levi has a huge fan following, and his death in a fanfic can be like losing a real friend for them. They might stop reading the fanfic altogether if they can't bear the thought of him being dead.
Eren would probably be very curious. He's always been eager to learn and understand new things. Meeting kids from another time would be fascinating for him. He might ask them a lot of questions about their world and how it differs from his. Levi, on the other hand, would be more guarded. He'd be suspicious at first, but once he realizes they're not a threat, he might start to warm up and show his more protective side towards the kids.
