In some cases, Sasuke might show a glimmer of regret. He realizes the value of Sakura too late. His character could start to show signs of trying to change for the better, in the hope of winning her back. However, this change may be slow and filled with internal struggles as he has to battle his own pride and past demons.
Sasuke might become more brooding and isolated. Without Sakura's positive influence, he could revert to his old, cold self. He may also become more reckless in his actions, not having Sakura to ground him.
In many Naruto harem fanfictions, Sakura often becomes more confident. Since she is part of Naruto's harem, she has a new - found sense of security and importance. For instance, in some stories, she no longer doubts her own abilities as much as in the original series.
In this fanfic, Sasuke's character would change in terms of his cold exterior. He would soften up a great deal. He might start smiling more often, especially when he is around Sakura. His actions would also be more focused on pleasing her rather than just his own goals. For instance, he might accompany Sakura to the hospital where she works just to be with her, which is a big change from his usually self - centered nature.
His loyalty shifts. Normally, Naruto is extremely loyal to his friends and village. But when brainwashed, he might turn against them. For example, he could start working for the enemy, believing that what they are doing is right.
The relationship might become more equal. Since Sakura is stronger, Sasuke can't look down on her as he might have in the original story. They could become more like true partners, respecting each other's abilities.
In some fanfictions, Sakura's curse mark makes her more determined. For example, if the curse mark is related to a powerful and dangerous force, she has to be strong - willed to keep it in check. This determination might lead her to train harder and become more confident in her abilities.
He could also become more vengeful. If Sakura's death was caused by an enemy, Sasuke would stop at nothing to avenge her. His focus would shift solely to seeking revenge, and his already formidable skills would be honed even further in his quest for retribution.
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.
Sasuke may also become more protective. When he watches Sakura in fanfic, he might see her in vulnerable situations. This could trigger his natural instinct to protect her, which gradually changes his cold - hearted image. For example, he could start to keep a closer eye on her during battles or when she is dealing with difficult patients if she is a medic - ninja. And this protection can lead to a deeper connection between them.
Sasuke might become more protective. Since Sakura is a princess, he feels a stronger sense of duty to keep her safe, which changes his usually aloof demeanor.
His understanding of relationships might grow. Through his interactions with Sakura, Sasuke could learn about compromise, forgiveness, and unconditional love. For example, he might learn to forgive himself for his past mistakes and understand that Sakura loves him despite all that.
