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.
On the other hand, Sasuke could be worried. He may think that Naruto is in some kind of trouble or danger. Given their history and the care they have for each other in the SasuNaru dynamic, Sasuke's concern could lead him to be more protective. He might start investigating the situation on his own to figure out why Naruto is hiding his face and ensure his safety.
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.
He could feel a sense of guilt. Sasuke might think that his actions or their relationship issues pushed Naruto to leave. He may then set out to find Naruto, not only to bring him back but also to resolve their long - standing issues. For example, if there were unspoken words or unresolved fights between them, Sasuke would see this as an opportunity to set things right.
Some popular Sasunaru fanfictions often include ones that focus on their unique bond and growth. 'The Road to Redemption' might be among the best as it delves deep into Sasuke's return and how Naruto helps him reintegrate. Another could be 'A Bond Beyond Comprehension' which shows their emotional connection in different challenging situations. And 'Friendship and More' explores the development of their relationship from friendship to something deeper in a really engaging way.
It depends on the specific fandom community. In some parts of the Naruto fandom, there might be a niche group that enjoys sasunaru sakura bashing fanfics. However, it's not likely to be mainstream popular as it involves bashing a major character, which can be off - putting to many fans.
In Sasunaru Sakura jealous fanfics, usually Sakura's jealousy adds an interesting layer of drama. It might be about her being jealous of the bond between Sasuke and Naruto. This could lead to various plot developments, like Sakura trying to come between them or realizing her own feelings in a different way.
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.
One of the best Sasunaru stories could be about their early days as rivals in the ninja academy. Naruto was always the outcast and Sasuke was the prodigy. Their constant bickering and small competitions were the start of a deep bond. For example, when they had a race to the top of the Hokage monument, Naruto's determination to beat Sasuke, even though he lost, showed his spirit and Sasuke's growing respect for Naruto.
