Well, the plot could be that Sasuke has been away on a long mission. When he comes back, he sees Sakura has become very close to Naruto in a different way. Sasuke starts to feel this twinge of jealousy because he realizes he might have lost his chance with Sakura. He then has to decide whether to confront his feelings or keep them buried.
A plot could be that Sakura and Sasuke are part of a ninja team for a special mission. There's another member on the team who has a crush on Sakura. This member is always trying to impress her. Sasuke, who has never fully acknowledged his feelings for Sakura, starts to feel jealous. He becomes overprotective of Sakura during the mission, which makes Sakura question his motives. As the mission progresses, their feelings of jealousy and attraction towards each other become more and more complex.
A fanfiction could involve a situation where both Sakura and Sasuke are dealing with jealousy in different ways. Sakura is jealous of the attention Sasuke gives to his ninja goals, while Sasuke is jealous of the friendships Sakura has with other guys. This creates a lot of tension and drama between them.
In many Sasuke - Hinata - Sakura fanfictions, Sakura's jealousy can be a complex and interesting aspect. It might stem from her long - held feelings for Sasuke. For example, if Hinata starts to get closer to Sasuke, Sakura could feel threatened. She might start to act out in ways that are out of character for her. Maybe she'll become more snippy or try to interfere in their relationship. Fanfiction writers often explore this dynamic to add drama and depth to the story.
A possible plot development is that Sasuke challenges the man Sakura is arranged to marry to a duel. If he wins, he demands that the arranged marriage be called off. Another is that Sakura, seeing Sasuke's jealousy, starts to have second thoughts about the arranged marriage herself.
Sakura's jealousy in these fanfictions can also be expressed through her words. She could make snide remarks about Hinata's relationship with Sasuke. Saying things like 'I don't see what he sees in you' or something along those lines. It adds a lot of tension to the story.
It could also lead to a situation where Sakura finally accepts her feelings and decides to move on. She might see that her jealousy is only causing her pain and that she should focus on herself and her own goals. This could open up new relationships and opportunities for her in the fanfiction, like finding a new love interest or achieving a long - term personal goal.
One possible plot could be that Sasuke gets injured during a mission and is brought to the hospital where Sakura works. Sakura then uses her medical skills to treat him, and during his recovery, they have deep conversations that rekindle their old feelings for each other.
Maybe Sasuke has been secretly planning the proposal for a long time. He starts by taking Sakura on a journey to different places they've been to in their past adventures. Along the way, he drops little hints. When they reach a beautiful, secluded spot by a waterfall, he gets down on one knee. He tells Sakura that she is the only one who has truly understood him and that he wants to spend the rest of his life with her. Sakura is shocked but then hugs him tightly and accepts.
Perhaps Sakura kidnaps Sasuke because she suspects he is in danger from some unseen enemy. She believes that by taking him away from the normal routine, she can protect him. She might have some inside information about a threat to Sasuke's life. In the process, Sasuke at first is angry with her for this drastic measure, but then realizes her good intentions as she reveals what she knows.
One possible plot could be Sasuke finally fully integrating back into the village after his long travels. Sakura and he have a daughter. The story could focus on Sasuke trying to be a good father, like teaching his daughter some basic ninja skills. He also has to learn to be more open with his emotions, which Sakura helps him with.
Another theme might be the exploration of Sasuke's character growth. His jealousy could be a sign of his changing emotions and his journey towards becoming more in touch with his feelings for Sakura. It can also show his possessiveness in a way, which is a complex aspect of his personality. In some fanfics, this jealousy might lead to conflicts between him and other characters who are close to Sakura.
