It could be a character from another important ninja clan, like Hinata perhaps. Since Hinata has always had feelings for Naruto and her clan is also a significant part of the village, Minato might see it as a good match.
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.
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.
Sakura could be a potential partner. Since they are friends from the original series, a forced marriage situation between them would bring a whole new dynamic. There would be a lot of room for exploring their relationship beyond just friendship.
One possible plot could be that Naruto is forced to marry a character from another village as a political alliance. This would create a lot of drama as he has to adjust to living with someone he barely knows while also dealing with the reactions from his friends in Konoha.
Well, in such a fanfiction, Naruto might initially resist the marriage. He could be in love with someone else, like Hinata perhaps. But due to some external factors, like a political deal or some strange village tradition, he's pushed into marrying Sakura. This could lead to a lot of tension between them at first, as Sakura might also be confused about her feelings, especially if she still has some lingering feelings for Sasuke.
One possible scenario is that Naruto, being forced to marry in the fanfiction, would initially be in a state of shock and disbelief. But then, his kind heart might make him consider the situation from the other person's perspective. He could end up trying to make the best of it, while still holding onto his ninja way. He might use this new situation to bring about some positive change, like uniting two warring clans through the marriage.
At first, the relationship would be rocky. Naruto and Sakura have different personalities and their own unrequited loves in the original story. But as they spend time together, they might start to find common ground. For example, their shared love for the village and their ninja way could bring them closer.
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.
If Naruto is forced to marry Itachi in fanfiction, the story could explore some deep themes. It could look at how two very different people can come together despite all odds. Itachi's guilt and his past actions could be a huge obstacle in their relationship. Naruto, on the other hand, would be bringing his own set of values like friendship and perseverance. The marriage could also have political implications within the Hidden Leaf Village. Maybe it was arranged for some strategic reason. This would force Naruto and Itachi to navigate not only their personal relationship but also the expectations and politics of the village.
