A potential plot twist could be that the arranged marriage was actually a ruse set up by an enemy. They might be planning to use the opportunity of the marriage to get closer to Naruto and somehow steal the Kyuubi's power.
One way to make it interesting is by exploring the power dynamics. Since Naruto has the Kyuubi within him, the arranged marriage could be a political move by the village elders to control that power. For example, they might arrange a marriage with a powerful clan's member to ensure loyalty and the proper use of the Kyuubi's strength.
In such a fanfiction, a possible idea is the development of the relationship between Naruto and the female character. It might start off rocky due to the arranged nature. But as they get to know each other, they could discover each other's strengths. For example, Naruto's determination and the female character's unique skills could complement each other.
Sakura could also be a candidate. Given her strong personality, she might initially resist the arranged marriage. But as she gets to know Naruto better and realizes the potential of the Kyuubi's power, she could warm up to the idea. Plus, it would create a lot of drama considering her previous relationship with Sasuke.
One possible scenario in such a fanfiction could be that Temari initially resists the arranged marriage. She is a strong - willed character from Suna. However, as she gets to know the other person (let's say Naruto for the sake of this fanfiction), she starts to see his good qualities. Maybe Naruto's determination and his ability to make friends easily start to win her over. They could go through various adventures together, which gradually makes their relationship more than just an arranged union.
One idea could be that Naruto is initially hesitant about the arranged marriage. He's so used to his freedom and his own way of life. But as he gets to know Hana, he discovers her kindness and loyalty, especially towards her ninja dogs. This makes him start to see the potential in their relationship.
Naruto is very outgoing and extroverted. He loves being around people and making friends. Artemis, on the other hand, is more reserved and independent, used to living in seclusion with her huntresses. So Naruto might constantly try to include Artemis in social situations that she would rather avoid.
To write this fanfiction, think about the setting. Since it's in the Naruto universe, you can include elements like ninja training and village politics. You could have Naruto teaching Hana some of his unique jutsu, and in the process, they start to bond. Also, don't forget to add some conflict. For example, some of Naruto's friends might not understand why he's in an arranged marriage, and Hana might face criticism from her clan for getting involved with an outsider like Naruto.
