Naruto would probably be really angry at first. He's a free - spirited person who doesn't like being forced into things. So he'd likely try to fight back right away, yelling at Sasuke about what he's doing.
The ninja community's reaction would be quite mixed. Some, like Naruto's close friends such as Shikamaru and Kakashi, would be supportive. They would likely offer their protection and assistance to Naruto during his pregnancy. However, there would also be those who are more traditional and might view Naruto's pregnancy as a weakness or something that goes against the norms of the ninja world. They could try to isolate Naruto or even oppose Sasuke's relationship with him because of it.
Sasuke might also be angry. Angry at the situation, angry at whoever or whatever caused Naruto's amnesia. His anger could fuel his determination to find a cure. He would push himself and Naruto harder in training, hoping that it would jog Naruto's memory, all while trying to hide his true feelings of worry and fear for Naruto's well - being.
Naruto may also try to find solutions. Despite the heartbreak, his optimistic nature might still shine through a bit. He could start to search for ways to mend the relationship with his parents, whether it's through magic in the Naruto world or by trying to prove his worth to them.
I'm not entirely sure specifically as it could vary greatly. 'Sasunaru' likely refers to a relationship between Sasuke and Naruto in a fan - created context. 'Abused' in this title might suggest a dark or difficult situation within the fanfiction, perhaps one character is being mistreated by the other in some way, but without reading it, it's hard to be more precise.
One common theme is the exploration of the alpha - omega dynamic between Sasuke and Naruto. It often involves Sasuke being the alpha and Naruto the omega, and how they interact with each other in this relationship.
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.
One popular 'sasunaru' fanfiction could be 'A Bond Tested'. In it, Sasuke's actions towards Naruto might be misconstrued as abuse in the complex relationship they share. It delves deep into their emotional turmoil and how they overcome it.
It could be that in the fanfiction, Naruto's character is developed in a way that Sakura, within the sasunaru concept, doesn't approve. For instance, if the fanfiction makes Naruto too weak or too different from his original self. Also, if the fanfiction focuses too much on certain relationships that she doesn't like, she would hate it.
One great Sasunaru Naruto fanfic is 'A Bond Beyond Comprehension'. It beautifully explores the deep relationship between Sasuke and Naruto. The story has amazing character development and the plot keeps you hooked from start to finish.
