If the grandfather is very warm and accepting, Shikaneji would feel relieved and happy. They might open up more about their relationship and their dreams. Nejire could start chatting excitedly about their future together, and Shinsou would relax and join in the conversation more. However, if the grandfather is not so friendly, they would be disappointed and perhaps a bit defensive.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
It could mean that a person who is a fan of 'Attack on Titan' (AOT) is reading or watching fan - created fictional works related to AOT. Maybe they are interested in seeing different interpretations or storylines that fans have come up with.
One way is to check on popular fanfiction websites. Look for ones with high ratings and a lot of reviews. For example, Archive of Our Own (AO3) has a large collection of AOT fanfictions. You can search for the most popular ones there.
It reimagines it by changing the genders of the main characters. So instead of a female mermaid longing for a human prince, it could be a male mermaid. This simple change can have a huge impact on the story's plot and relationships.
It changes the relationships. For example, if Luke was female, her relationship with Vader would have a different undertone. It could be more of a father - daughter dynamic, which might make Vader's redemption more about paternal love. Also, if Han was female, the flirting dynamic with Leia would be reversed, adding new comedic and romantic elements.
In a genderbend story, the main character is a merman instead of a mermaid. This changes the dynamic of the relationship with the human character. For example, in the original, it was a mermaid falling for a human prince, but in the genderbend, it's a merman falling for a human princess or prince. Also, the challenges faced might be different as male and female characters often have different societal expectations, even in a fictional underwater and human world setting.
The impact on the Starco relationship in genderbend fanfiction also lies in the way their individual growth is portrayed. When their genders are swapped, their character arcs related to the relationship might change. For instance, Marco as a female might face different challenges in the relationship compared to his male self, and these challenges can shape the relationship in a whole new way, either bringing them closer or creating more distance depending on how the fanfic writer decides to develop it.
