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.
"The Prince of Time Traversal Is Too Impatient." This was an ancient romance novel about a 26-year-old mature woman who transmigrated into a 13-year-old girl, and her life became a tragedy. She was the heir of the 108th generation of the Heiye family. Her medical skills and poison techniques were a piece of cake, and she was even better at disguising herself with martial arts. However, the emperor had decreed that she should be happy, and she had to face the harassment of the sick prince. As a fake wife, she still had to help her husband deal with all kinds of troublesome matters. In the end, the sunny and beautiful man and the golden-masked man suddenly appeared.
Yes, there are some fanfictions with this rather strange premise. You can often find them on various fanfiction websites like Archive of Our Own (AO3). Just search for the relevant tags.
One popular 'Naruto Forced to Marry' fanfic could be 'Naruto's Unwanted Union'. It might explore how Naruto, who is used to his freedom, copes with the sudden situation of being forced into marriage. It could involve his struggles with his ninja duties and new family responsibilities.
I recommend the novel "Reborn in the Early Years of Kangxi". The female protagonist was reborn in the Kangxi era. Her aunt was the empress of Emperor Shunzhi. She herself became the empress of Kangxi and gave birth to Emperor Yongzheng. This novel was not a palace novel. The female protagonist's father was an official in a foreign country and was not valued by the family. I hope you like this fairy's recommendation. Muah ~😗
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.
It could be a jealous demigod. Maybe someone who has always been envious of Percy and Annabeth's relationship and popularity. This person finds a way to manipulate some dark magic or an old rule to force them into marriage, hoping to create chaos in their lives.
In 'Markson Mark is forced to marry fanfiction', a common theme is the clash between personal will and external forces. Mark's own desires and plans are disrupted by the forced marriage. Another theme is adaptation. He has to adapt to the new situation of being married. There may also be themes of betrayal if there are elements where someone is behind the forced marriage for ulterior motives. And of course, the theme of redemption could also play a part if Mark or the other character tries to make up for the wrongs in the situation.
Yes, I recommend "The Substitute Married Princess Is a Beggar". It was an ancient romance novel about a beggar's soul transmigrating into the Prime Minister's daughter, marrying her as a substitute concubine, and how he survived in the back of the Prince's mansion.
