One popular theme is the exploration of their relationship in alternate universes. For example, in some fanfictions, they might be in a modern setting rather than the original Fate/stay night universe. Another theme could be the growth of their bond through various challenges. They might face new enemies together, which deepens their connection. Also, the theme of self - discovery within their relationship is common. As they interact more, they learn more about themselves and what they truly want from each other.
In the canon, their relationship is more restrained. But in lemon fanfiction, it often explores a more passionate and romantic side of their relationship. Canon focuses on the overall story and battles, while the fanfiction delves deeper into their personal feelings for each other.
In fanfiction, Shirou and Saber's love is often depicted as a complex and beautiful relationship. It's a love that transcends their different natures. Shirou, with his strong sense of justice, is drawn to Saber's noble and powerful presence. Their love story can be full of moments of understanding and mutual growth.
One common theme is love. Their relationship is often explored in different ways, from a slow - burn romance to an instant connection. Another theme is loyalty. They are both loyal characters, and in fanfiction, this loyalty is often tested and reaffirmed.
Well, I'm not sure about specific 'lemon' fanfics as they might contain inappropriate content. However, you can try looking on some well - known fanfic platforms like FanFiction.net or Archive of Our Own. Search for works related to Shirou and Saber in the general category and then filter out the ones that meet your interests while also ensuring they follow the platform's rules.
Character development is crucial too. If the fanfiction shows how Saber and Shirou have grown as individuals and as a couple, the kiss becomes more meaningful. It could be that through various trials, they have come to understand and love each other more deeply, and the kiss is a physical manifestation of that.
Growth is also a prevalent theme. Both characters grow as individuals within their marriage. Shirou might become more confident and assertive, while Saber may learn to be more open and emotional. This is often shown through various events in their married life in the fanfiction, like dealing with financial issues or making big decisions together.
There's a fanfiction called 'Married Bliss: Shirou and Saber'. In this story, they get married and start a family. It focuses on how Saber adapts to a more peaceful life, away from the battles she was used to. Shirou is always there to support her, and their love for each other just grows stronger with each passing day.
Perhaps they face challenges from the magical world. Since Saber has a connection to the throne of heroes, there could be threats from other entities who don't want a married Saber. They would have to fight together to protect their relationship and their new life. Meanwhile, they are also growing closer and deeper in love as they face these difficulties side by side.
