Perhaps in the fanfiction, Naruto saves Temari from a great danger. This heroic act makes Temari see Naruto in a new light. They begin to spend more time together, training or just talking. As time passes, their friendship turns into love, and they decide to marry, uniting the Leaf and Sand villages in a new way.
A plot twist could also be that Temari discovers a long - lost relative who has a dark past and tries to use Naruto's influence for evil purposes. Temari would be torn between family loyalty and her love for Naruto, and Naruto would have to help her make the right decision while also protecting their relationship and the villages.
In some fanfictions, Naruto could be facing a powerful enemy that he underestimated. Temari steps in and saves him. This event could then trigger a series of events where Naruto starts to study Temari's fighting style to improve his own skills. At the same time, the two of them could get involved in some political intrigue within the ninja villages, as Temari is from Suna and Naruto is from Konoha. Their relationship could be a key factor in the stability between the two villages.
A possible plotline could be that Naruto is chosen by Kami for some greater purpose related to the balance of the world. As a result, they get married. Their union then brings about a new era of peace and prosperity as Naruto uses Kami's power to end all wars. Another plotline might be that Kami falls in love with Naruto's pure heart and determination. She decides to marry him, but they first have to convince the shinobi world that their union is for the good of all.
Maybe there's a plotline where Naruto is arranged to marry someone from the Rookie 9 for political reasons in the village. At first, they might be reluctant, but as they get to know each other better, they truly fall in love and build a strong marriage. This could involve them working together to improve the village's relations with other villages through their union.
A Naruto marries Temari fanfiction could be full of cultural exchanges. Since Naruto is from Konoha and Temari is from Suna. Their marriage might bring the two villages closer in terms of trade, ninja training exchanges, etc. For example, Konoha could share some of its unique jutsu training methods with Suna, and Suna could offer its knowledge on desert survival and sand - based jutsu.
Gaara, Temari's brother, would surely be a significant supporting character. He would be involved in the decision - making regarding Temari's marriage. Hinata could also be a part of it, maybe as a friend to Naruto, offering her gentle support and understanding throughout Naruto's relationship journey with Temari.
If Temari is feeling stressed about her role as a shinobi in diplomatic matters, Naruto could offer his own perspective. He might say 'I'm not always good at the political stuff either, but I've learned that being true to yourself and your village is the most important thing. You're doing great, and everyone can see your strength and determination.' This would boost Temari's confidence and comfort her in her role.
Well, perhaps there could be a plotline where Ranma is in a life - or - death situation and Happosai saves him. In gratitude, Ranma agrees to marry him, but then has second thoughts later. Or it could be that a mischievous character plays a trick on them and they end up married, and the rest of the story is about them trying to figure out how to undo it or make the best of it.
One possible plotline could be that in a post - war world, Narcissa and Harry find themselves drawn to each other through mutual understanding. Maybe Harry sees a different side of Narcissa that was hidden during the war, and they start to build a relationship from there that leads to marriage.
In some 'Harry Marries Lucius' fanfictions, it might start with a completely different wizarding world setting. For example, a world where the traditional enmities between the Gryffindors and the Slytherins are not as strong. Harry and Lucius could meet under different circumstances, like at a diplomatic event. Their relationship could then be a slow - burn one, with them having to navigate through cultural differences, power struggles within the wizarding world, and their own personal demons. This could all lead to their marriage and the subsequent development of their relationship.
