Some fanfictions might center around Sasuke and Sakura's family life. For example, how they raise their children in a shinobi world filled with challenges. There are also those that rewrite the original story's ending to give them a more romantic and fulfilling relationship. A good number of fanfictions also explore the idea of Sasuke finally fully opening up to Sakura and sharing all his secrets with her.
One of the main themes is the struggle between duty and personal desires. Sakura has her duties in the village and her love for Sasuke which can sometimes conflict. For Sasuke, his loyalty to his own goals and how that relates to his connection with Sakura. Also, the theme of forgiveness is quite common. Sakura has to forgive Sasuke for leaving her in the past, and Sasuke has to forgive the village for what he perceives as wrongs done to him.

One great Sakura and Sasuke manga fanfiction is 'The Unseen Bond'. It delves deep into their relationship post - the main Naruto storyline. It shows how they grow together and support each other in rebuilding the Hidden Leaf Village. Another one is 'Sakura's Redemption'. This fanfiction focuses on Sakura's journey to prove herself worthy of Sasuke's love and respect. She undertakes difficult missions and training, all while Sasuke is away on his own personal quests.
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.
Sasuke could initially be a vampire who is full of anger and resentment, maybe because of how he was turned. But Sakura's positive attitude and kindness could start to soften him. He might start to open up about his past and his feelings. Sakura could develop from a somewhat naive vampire into a more worldly and wise one. She would learn about the darker side of the vampire world through Sasuke, and this would change her. Maybe she would become more cynical at first, but then find a balance between her old self and the new knowledge she has gained.
In proper fanfics rather than 'lemon' ones (as 'lemon' implies inappropriate content), Naruto is known for his never - give - up attitude. He's the heart of the story, always trying to bring Sasuke back and protect his friends. Sasuke is a complex character, with his family's past haunting him, which makes him seek power and revenge at times. Sakura, she starts as a girl with a crush but evolves into a capable ninja. These characteristics are often the foundation for fanfic authors to create interesting stories that don't involve improper content.
In these fanfics, one characteristic is the growth of their relationship. At first, Sasuke may be aloof, but gradually he opens up to Sakura. Sakura, on the other hand, is always steadfast in her love. Another is the mutual support. They often face difficulties together, be it in battles or in rebuilding their world, and they rely on each other's strength. Also, there's the element of deep understanding. They come to understand each other's past traumas and insecurities, which brings them closer.
For Sakura, she could grow in terms of her leadership skills. If they encounter any difficulties in the forest like being chased by a group of wild animals or getting caught in a dangerous situation, she could step up and lead the way out. Sasuke might then realize that Sakura has the potential to be a great leader. And for Sasuke himself, he could become more open to the idea of a relationship with Sakura. The seclusion of the forest could provide the perfect backdrop for him to explore his feelings for her.
