Since 'hard lemon' fanfiction is inappropriate, we can talk about their general characteristics in normal fanfiction. Sasuke is often depicted as a brooding and powerful character, while Sakura is shown as strong - willed and loving. In non - inappropriate fanfiction, their relationship might be shown as evolving from initial acquaintance to deep love, with Sasuke's cold exterior gradually melting due to Sakura's unwavering affection.
Naruto is often a popular character in these fanfictions. He could be Sasuke's rival for Sakura's attention or a good friend who tries to help them get together. Ino is also a common character. She might be Sakura's friend or sometimes a rival in matters related to Sasuke. Kakashi could be their teacher who gives them advice about their relationships and schoolwork.
In the hospital setting, Sasuke might initially be his aloof self. But as Sakura takes care of him or they face challenges together, he could start to open up more. For example, if Sakura is overworked, Sasuke might offer a helping hand in small ways, like getting her coffee. This would show his growing affection for her.
Their relationship can be shown as one filled with deep love and care. Sasuke, who has always been a bit aloof, becomes much more tender and attentive towards Sakura during her pregnancy. He might start doing small things like getting her favorite foods or just sitting with her and talking about their future as a family.
Sakura might develop into a more confident and assertive person. After the war, she has proven herself as a strong kunoichi, and with Sasuke by her side, she could grow even more. Sasuke, on the other hand, would develop by learning to trust and love again. He has been through so much, but with Sakura's love and support, he could become a more stable and caring person.
The relationship can also be developed through their interactions with other characters. For instance, if they have a child, how they both interact with the child and how their parenting styles differ and blend. Also, how they interact with their friends like Naruto and Hinata. Maybe they have double dates or group outings. All these interactions can show different aspects of their relationship and how it grows and evolves over time.
In some fanfictions, there are scenes where Sakura is in danger and Sasuke realizes just how much she means to him. For example, if Sakura is injured while protecting Sasuke, Sasuke's reaction of guilt and his newfound determination to always be by her side can be an extremely emotional part of the story.
The relationship often becomes more strained. Sasuke's punishment can make Sakura feel resentful at first. But over time, it can also lead to her becoming more independent as she tries to prove herself to him.
In the realm of fanfiction, almost any scenario is possible. Regarding Sasuke divorcing Sakura for Karin, it may exist. Fanfiction authors draw inspiration from the source material and then take it in new directions. The idea might stem from Karin's past feelings for Sasuke and some fans' desire to see how such a relationship shift would impact the characters. It could also be a way to explore the characters' personalities more deeply, for example, how Sakura would cope with such a betrayal and how Karin would handle being with Sasuke in that context.
Yes, there might be such fanfictions in the Naruto fanfiction community. However, it goes against the original intention of many fans who support Sasuke and Sakura's relationship. Fanfictions can explore various alternative storylines, but this kind of plot often causes controversy among fans.
