It could end with a draw. They both realize that they are equally matched and that their fight is not really getting them anywhere. They might then decide to have a more civilized conversation to resolve their differences.
Sasuke might win the fight physically, but in the end, he realizes that he has lost something more important like Sakura's trust or friendship. This could lead to him having a change of heart and trying to make amends for his actions during the fight.
It could make their relationship stronger in the long run. After the fight, they might realize how much they actually care about each other. They could start to communicate better and understand each other's perspectives more deeply.
In many fanfictions, Sakura might choose Sasuke. They have a long - established relationship, with Sasuke being someone she has loved since childhood. Her feelings for him are deep - rooted and often in fan - created stories, she remains loyal to those initial feelings.
Their relationships could develop in a more positive way. Through fighting together, they start to understand each other better. Naruto and Sasuke might finally put aside their old rivalries completely. Sakura could gain more respect from both of them as she shows her strength and intelligence in battle.
Their relationship could become more strained. Sakura might be afraid of Sasuke after the bite, creating distance between them. Sasuke, on the other hand, could be filled with regret and try to avoid her, which would further complicate their relationship.
Their relationship would likely become more intimate and committed. With a baby on the way, Sasuke would feel a greater sense of responsibility towards Sakura. He might be more protective and stay closer to 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.
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.
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.
Maybe it's about protecting Sakura. Itachi might think that Sasuke isn't the right person for Sakura and wants to protect her from Sasuke's darker side. And Sasuke, on the other hand, believes he can protect Sakura better than Itachi and that Itachi has no right to interfere.
Sakura would be over the moon. She would blush deeply and look at Sasuke with so much love in her eyes. She might be at a loss for words for a moment, but then she would find her voice and tell Sasuke that she has been waiting for this moment her whole life. She would also feel a sense of pride that Sasuke has chosen her, after all they have been through. And she would immediately start thinking about how to share the good news with their friends, especially Naruto, who has been like a brother to her and has also been a part of their journey.
