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.
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.
Well, Sasuke could show his jealousy in a more subtle way too. He might start training harder or trying to outdo Naruto in certain skills when he feels threatened by someone else's relationship with Naruto. Sometimes, he might give Naruto the cold shoulder but then secretly keep an eye on him to see who he's with. It's all about that complex dynamic between them in the fanfiction world.
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.
Another theme is unrequited friendship. Naruto sees Sasuke as his closest friend, but Sasuke's actions sometimes make Naruto feel like that friendship is not mutual, leading to hurt feelings. It's often about Naruto's struggle to hold on to that friendship in the face of Sasuke's coldness.
One popular one could be 'The Bond Beyond Battle'. In this fanfiction, Sasuke's decision to save Naruto is driven by a deep understanding of their shared past and the unspoken bond between them. It beautifully portrays Sasuke's internal struggle and his ultimate choice to put Naruto's life above all else.
Well, 'Pain of the Promise' is a fanfiction in this category. Here, Sasuke breaks a significant promise to Naruto which hurts him badly. It delves into Naruto's inner turmoil as he copes with this new reality and how it affects their relationship.
One common element is their strong bond of friendship. In many fanfictions, they start as friends who understand each other deeply. Another is their mutual growth. They might grow together as ninjas, learning from each other's skills and experiences. Also, there could be elements of adventure where they embark on missions together and rely on each other's strengths.
