At first, Naruto would be in disbelief. She has always seen Sasuke as a friend or a rival, not a marriage partner. So, she would likely be very vocal about her opposition. She might gather her friends, like Sakura and Kakashi, to support her cause. She could also try to appeal to Sasuke's sense of justice. Since Sasuke has his own code of ethics, he might also not be happy about this forced situation. Naruto could use this to try and find a way to break free from this unwanted marriage.
However, as the story progresses, he may start to see the benefits of the relationship. Maybe he realizes that Sakura can be a strong ally and a source of emotional support. He might gradually open up to her, starting with small gestures like sharing his thoughts or protecting her during battles.
One reason could be political. Maybe the two clans or villages that Naruto and Sasuke are associated with want to strengthen their alliance. By marrying their most powerful members, they hope to ensure peace and cooperation.
Well, at first it would be really rocky. Naruto might be angry and resentful towards Sasuke for forcing him into this situation. But as time goes on, they could start to understand each other better. Sasuke might realize the harshness of his actions, and Naruto could see that Sasuke had some deeper reasons, perhaps related to protecting Naruto in his own twisted way. Eventually, they might find a way to build a real relationship based on mutual respect and love that grows from their shared experiences.
It could be someone from a rival village. Maybe as part of a peace treaty, Naruto is forced to marry a kunoichi from a village that was once at war with Konoha. This would create a lot of tension and interesting storylines as Naruto has to deal with the cultural differences and the past hostilities between the two villages.
Initially, Naruto would likely try to find a way out of the marriage. But as time passes, he realizes that fem Sasuke is also a victim of this forced situation. They might start to communicate more, sharing their thoughts and feelings. Fem Sasuke could learn about Naruto's big heart and his dreams for the ninja world. Naruto, on the other hand, would understand fem Sasuke's past and her own desires. This mutual understanding would transform their relationship from a forced one to a more loving and respectful partnership.
Well, it could be that an ancient prophecy in the Naruto world dictates that Naruto and fem Sasuke must marry. Naruto might be in a tough situation because he has his own dreams and goals. However, fem Sasuke could also have her own reasons for going along with it. Maybe she wants to use this opportunity to change the ninja world in some way. As they live together, they'll face many challenges from their friends and family who might not be fully on board with this arrangement, but they could grow closer through these difficulties.
Naruto would probably be extremely confused at first. He has always seen Itachi as a complex figure, and suddenly being forced to marry him would be a huge shock. He might feel angry that he has no say in this. Itachi, on the other hand, would likely be stoic on the surface but internally be very conflicted. He has his own burdens and this unexpected situation would add to them.
In these fanfictions, character development can also be seen in how Naruto and Sasuke handle the external pressures related to their marriage. Naruto, being the more positive one, could inspire Sasuke to face the world with a more optimistic attitude. And Sasuke's determination could rub off on Naruto, making him more focused. Their individual growth is intertwined with their relationship growth. For instance, they might start to train together more often, sharing their skills and knowledge, which not only improves their ninja abilities but also deepens their bond.
Naruto might initially be shocked. Given his friendly nature towards Sasuke in the original story, he wouldn't expect such an attack from her. So, his first reaction could be pure disbelief.
At first, it would be really awkward. Naruto might be all over the place, trying to make the best of the situation, while Sasuke would be cold and distant. But as time passes, they would start to communicate more. Naruto's positive attitude might slowly break down Sasuke's walls. They could start training together again, like old times, but with a new layer of closeness. Eventually, they might develop a deep respect and love for each other that goes beyond friendship.
