It could be due to Sakura's feelings for Sasuke. If she's overly focused on Sasuke and Naruto gets in the way of her plans regarding Sasuke in some way, she might lash out and hurt Naruto without really meaning to cause serious harm.
I like 'The Comfort After the Storm'. This fanfic focuses on Sakura dealing with Naruto's emotional pain after he loses a very important person. Sakura is there for him, and they have some really heart - to - heart conversations. It shows how their relationship can be so much more than just teammates.
In some Sasunaru fanfictions, Sakura might hurt Naruto emotionally. For example, if she chooses Sasuke over Naruto in a very cruel way, it can break Naruto's heart. She could say mean things about his dreams or his past as an orphan, which would deeply wound him.
Character development. A good fanfic in this genre should show how Naruto and Sakura grow from the hurt they experience. For example, if Naruto is physically hurt, it could lead to him becoming more cautious or Sakura learning new medical techniques to better protect him.
When writing a Naruto Sakura hurt comfort fanfiction, consider the setting. It could be in the middle of a war - torn battlefield, where Sakura is physically and emotionally drained. Naruto could comfort her by simply being there, holding her hand and assuring her that they will get through this together. Another aspect is the dialogue. Make it sound like Naruto and Sakura. Naruto might say something like 'Sakura - chan, you're the toughest person I know. This is just a little setback.' Use these elements to create a compelling story.
One great example could be a story where Sakura gets injured during a battle and Naruto is there to comfort her. He might use his own experiences of being hurt and alone to make her feel better. For instance, he could tell her about how he felt when he was ostracized as a child, and how he overcame those feelings. This kind of shared vulnerability can be really comforting in a fanfiction.
It could be due to a clash of ideals. Gaara, having grown up in a harsh desert environment and with his own set of values as the Kazekage, might not see eye - to - eye with Sakura's more compassionate and medical - focused approach. This difference could lead to an argument that escalates and results in him hurting her.
One common theme could be self - sacrifice. Sakura might get hurt while trying to protect someone she cares about. Another theme could be heartbreak, like when she is betrayed in a relationship and that causes her emotional pain.
Perhaps in the fanfiction, there is a plot twist where Sakura has been brainwashed by an antagonist. The antagonist could be using her to get to Naruto, knowing their close relationship. So, she would then be made to attack Naruto without her own will. Or, there could be a prophecy or some sort of pre - determined fate in the fanfiction's plot that causes Sakura to hurt Naruto, even if she doesn't really want to.
There could be fear as well. Seeing Naruto injured, Sakura might be afraid of losing him. This fear could drive her actions in the fanfiction, whether it's in finding a cure for his injuries or in taking revenge on those who hurt him. It would also add more depth to their relationship as she grapples with these complex emotions.
