One scenario could be that Naruto gets hurt while trying to save Sasuke from a dangerous situation. Sasuke then feels guilty and starts to realize how much Naruto truly means to him. In the fanfiction world, this might prompt Sasuke to be more open about his feelings towards Naruto, which could range from deep friendship to something more romantic. The hurt Naruto endures can be a turning point in their relationship, making Sasuke re - evaluate his actions and priorities.
A common plotline is Naruto getting hurt during a mission. Sasuke then blames himself if he wasn't there to protect Naruto. He might vow to become stronger so that he can always be by Naruto's side in future missions. Another is when Naruto is hurt by an enemy who specifically targets him because of his status as a Jinchuriki. Sasuke will then go on a revenge spree to take down the enemy.
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.
The popularity of Sasunaru Naruto hurt fanfiction lies in the complex relationship between Sasuke and Naruto in the original series. Their relationship has so many layers, from friendship to rivalry, and fans love to explore the darker, more painful aspects of it. It gives writers a chance to dig deeper into the characters' emotions and show how they can be broken and mended.
One good Sasunaru Naruto hurt fanfiction is 'Broken Promises'. It delves deep into the pain and misunderstandings between Sasuke and Naruto. The story shows how their relationship is strained due to various events in the Naruto universe. Another one is 'Scarred Hearts' which focuses on the emotional wounds they carry and how they try to heal while still being at odds with each other.
One possible reason could be a misunderstanding. Maybe Naruto was misidentified as a threat in a tense situation. For example, if there was some sort of dark jutsu at play that clouded Kurenai's judgment and made Naruto seem like an enemy. Another reason might be that Kurenai was under some sort of mind - control. There are many villains in the Naruto universe who are capable of such things. If she was being controlled, she might unknowingly attack Naruto.
A really popular one is 'Sasunaru: The Unbreakable Link'. In this fanfiction, the author focuses on the psychological aspects of their relationship. It shows how their past traumas have shaped their bond. There are many intense scenes where they have to confront their inner demons together, which makes for a very engaging read.
Naruto might get hurt during a mission with Kaka - naru. Kaka - naru could then carry Naruto back to safety and tend to his wounds. This simple act of care can strengthen their bond.
Another situation is when Kakashi is on a solo mission. He might encounter a group of powerful opponents who manage to wound him. This forces him to rely on his wits and basic ninja skills to survive while waiting for backup. It can show his resourcefulness even when injured.
Physical hurt might come from a powerful magic spell. Let's say an evil sorcerer casts a spell that drains Yami's energy and causes him pain. His struggle to overcome this and regain his strength could be a central part of the fanfiction.
