Sakura might become more empathetic. Seeing Naruto's memories would expose her to his pain and his hopes, so she would be more understanding of his actions and decisions.
Naruto would probably be more self - disciplined. Sakura is known for her self - control, and she'd pass this on to Naruto. So he might not be as wild - spirited as in the original.
Sakura may react with a sense of urgency. She would drop whatever she was doing and rush to Naruto's side. She'd be worried that something truly terrible has happened. If Naruto is hesitant to talk, Sakura might just sit quietly with him, waiting for him to open up. This would show her patience and understanding, and also how much she values Naruto as a friend.
Sakura's character could develop in terms of her emotional intelligence. She might break free from her insecurities and jealousies. For instance, she realizes that her feelings for Sasuke were more of an infatuation based on his popularity rather than true love. So she focuses on building a deeper and more meaningful connection with Naruto. She learns to understand his dreams and goals better and supports him in a more effective way, which in turn makes her a more well - rounded and likable character.
One possible plot could be that Sakura gains a new understanding of Naruto's struggles and his past traumas. This might lead to her seeing him in a completely different light, perhaps strengthening their friendship or even leading to some romantic feelings if the fanfiction takes that route.
Her character could develop in a way that she becomes more independent. In the fanfiction, away from the protection of her usual teammates, she has to fend for herself among Orochimaru's minions. This would force her to rely on her own strength and intelligence. Also, she might develop a darker side. Being around Orochimaru's evil influence, she could struggle with maintaining her positive outlook and might have moments where she is tempted by the power he offers without considering the consequences.
Sakura's character would likely become more confident. Being an Uchiha gives her access to powerful abilities and a certain status within the Naruto world. This new - found power could boost her self - esteem which was sometimes lacking in her original self. She would also become more in - tune with the darker aspects of the Naruto universe as the Uchiha have a tragic history.
Sakura's character could develop in a more empathetic way. Since Naruto has been so open with his feelings, she might start to look at the world from his perspective more often. She may become more aware of how her actions towards Naruto, whether it was her focus on Sasuke in the past, affected him.
Naruto would likely develop a more serious side. He's used to chasing after Sakura's love in a more light - hearted way, but in a forced marriage, he'd have to step up and be more responsible for her well - being. Sakura would become more understanding of Naruto. She might start to see past her long - held feelings for Sasuke and notice Naruto's true qualities like his loyalty and selflessness. Their relationship would be a journey of self - discovery for both of them.
Sakura would likely become more solemn. She might lose some of her more light - hearted qualities as the grief of Naruto's death weighs on her. For example, she may stop making her usual jokes.
She could develop a more strategic mind. Shisui and Itachi are known for their intelligence in battle. Sakura would learn from them how to analyze situations better, plan ahead, and anticipate her opponents' moves. This would make her a more well - rounded ninja rather than just relying on her brute strength.
