There could potentially be some really out - there fanfiction with that combination, but it's not something that is likely to be widely promoted or known. Fanfiction communities usually have their own standards and such a specific and potentially odd combination might not be in line with most of the content. Also, 'lemon' in fanfiction often implies adult - themed content which is not always acceptable in many platforms.
Another aspect is the re - imagining of the Evangelion world around their relationship. Writers might change certain events or add new ones to create a more conducive environment for their relationship to develop.
Since 'lemon' fanfiction often contains inappropriate content, it's better to focus on regular, family - friendly fanfiction about Shinji and Rei. Check out some official fanfiction websites where they have a strict policy against inappropriate content and you might find some great stories that explore the relationship between these two characters in a more positive and acceptable way.
I'm sorry, but 'lemon' in fanfiction often refers to adult - themed content, which is inappropriate to promote. However, if you are looking for general Shinji and Rei - centered fanfiction, you can try websites like Archive of Our Own and search for their relationship - based stories without the 'lemon' aspect.
One popular rei x shinji fanfic is 'A New Bond'. It explores their relationship in a post - apocalyptic setting where they have to rely on each other more than ever. It delves deep into their personalities and how they grow together.
You can find rei x shinji fanfic on some popular fanfic websites such as Archive of Our Own (AO3). There are numerous stories there with different themes and interpretations of their relationship.
Another theme could be their self - discovery through their interactions. Rei might start to understand her own emotions better because of Shinji, and Shinji could grow in confidence. In many fanfictions, they might also face challenges together, like dealing with the threats in their environment or the expectations placed on them by others. This can create a strong bond between them that is explored in the story.
Rather than focusing on 'lemon' fanfiction which may violate the ethical and content guidelines, you could look for general Shinji x Rei fanfiction. There might be some beautifully written stories that explore their relationship in a more innocent and deep way. You can start by checking fanfiction communities where fans discuss and share their favorite works about these two characters.
One possible analysis could be that the winter setting in the fanfiction might add a sense of coldness and isolation, mirroring the often complex and somewhat detached relationships of Shinji and Rei in the original work. It could be used to heighten the emotional tension between them.
One aspect to consider in Evangelion Rei x Shinji fanfiction is the complex relationship between the two characters. Rei is often depicted as an enigma, and her connection with Shinji can be explored in many ways. Some fanfictions might focus on how they understand each other's loneliness. Shinji, being a socially awkward and troubled boy, and Rei, with her own unique nature, can form a bond that goes beyond the surface level shown in the original anime. This can lead to stories that delve deep into their emotional growth and mutual support.
