Well, they might be shocked at how much technology has advanced in the future depicted in the fanfiction. Maybe there are new types of elemental powers or different ways of training ninjas. It could also be that the relationships between characters have changed in unexpected ways, and they would have to come to terms with that.
He might be shocked. In the fanfic, if he sees things like his friends' future achievements or the new threats that emerge, it would surely startle him. For example, if he discovers that one of his friends has a family of their own and has become a great leader in the village, he would be proud but also a bit surprised at how much has changed.
They might gain a new perspective on their own abilities. If the future fanfiction shows ninjas with enhanced powers, the past characters could start to think about how they could develop their skills further. For example, if in the future they can combine elemental powers in new ways, the past ninjas might start experimenting.
With his usual determination. Naruto has always been one to face difficulties head - on. So, even if he's shocked by what he sees in the fanfic's future, he'll likely try to find solutions immediately.
Their relationship would likely be more complex in the past. Since they are from the future and already married, they would have a deeper connection. But they would also have to hide it from their past selves. Naruto might be more protective of Sakura in the past, and Sakura would be more confident in their relationship.
In many Sakura Naruto fanfics, Sakura is often depicted as a strong - willed character. She uses her medical skills not only for healing but also for strategic purposes during battles.
When it comes to Sakura's secret past in fanfiction, it can range from her early days in school before she became well - known in her field. Maybe she had a secret admirer that she didn't know about, or she was part of a small group that was working on a special project. Fanfiction allows for these unique and often unthought - of scenarios to be explored.
On Naruto's side, he would probably feel guilty after realizing what he had done. This guilt could make him try to make amends, but Sakura's initial reaction of anger and hurt would still be a big obstacle in their relationship. Their interactions would be filled with tension and awkwardness.
One possible reason could be that she might have underestimated Naruto in the past. She often belittled his abilities and dreams, but as she grew and realized his true strength and determination, she felt the need to apologize for her previous behavior.
