In such fanfiction, their relationship could be shown as a complex web of emotions. They might have a lot of unspoken feelings that surface in the 'dark' situations they face. For example, when they are in a dangerous battle, Sasuke might show his protective side towards Sakura in a more aggressive way than usual, which could lead to some intense moments between them. The 'lemon' aspect could add a layer of physical passion to their relationship, but it should be done in a way that still respects the characters' core personalities.
In a Sasuke and Sakura jealous lemon fanfiction, their relationship can be a rollercoaster. Jealousy can be used to explore their insecurities. Sasuke, who has always been a bit of a lone wolf, might be jealous because he's not used to sharing Sakura's attention. Sakura, who has loved Sasuke for a long time, could be jealous when she feels she's not the most important person to him. As they deal with these jealous feelings, they learn more about each other and their relationship deepens. For instance, they might start to communicate more openly about their feelings, which was something they struggled with before. This new - found communication can lead to more romantic and intimate moments in the fanfiction.
In a sleeping fanfiction, their relationship can be shown through small gestures. For example, Sasuke might unconsciously reach out for Sakura in his sleep, indicating a subconscious need for her presence. It could also be that Sakura curls up closer to Sasuke while sleeping, showing her trust and love for him.
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.
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.
Another way is to show their relationship as a power struggle. In the dark fanfiction, Sasuke could have new powers that make him a threat, and Sakura, not willing to be overshadowed, tries to gain equal or greater power. Their relationship then becomes about who is stronger and who will ultimately control the situation, all while their underlying feelings for each other still exist in a distorted way.
Sound in fanfiction about Sasuke and Sakura's relationship can be very symbolic. The howling of the wind during a stormy encounter between them might represent the chaos in their relationship at that time. But then, the sound of a bird singing after they resolve an issue could symbolize new hope. The whispering between them in a quiet moment can be full of unspoken feelings, which is a crucial aspect of their relationship as it unfolds in fanfiction.
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.
Well, they could start with Sasuke being hesitant about the pregnancy at first, but then as he sees Sakura's determination and love, he warms up to the idea. This could strengthen their bond.
The shared goal of dealing with the thief can also lead to them seeing new sides of each other. Sasuke might see Sakura's determination and courage in a new light, while Sakura could observe Sasuke's more protective and caring side. This new understanding can deepen their relationship.
The relationship can start with a moment of vulnerability. For example, if Sakura is in a dangerous situation and Sasuke comes to her rescue. His licking of her (in a non - sexual, affectionate way like licking a wound) can be the first sign of his deeper care for her. This could lead to Sakura realizing that Sasuke's feelings for her have changed, and she starts to open up more to him.
