One possible plot could be that Itachi, after leaving the Akatsuki and resolving his issues, meets Hinata. Hinata, with her kind heart, helps Itachi adjust to a normal life. They gradually fall in love and decide to get married. Their wedding could be a small, private affair with only their closest friends present, like Naruto and Shikamaru for Itachi, and Sakura and Ino for Hinata.
Well, in this fanfiction plot, perhaps there is some sort of mission that brings Itachi and Hinata together. They start off as comrades during the mission, learning about each other's strengths and weaknesses. Hinata is initially shy around Itachi, but as they face challenges together, she becomes more confident. Itachi, on the other hand, is drawn to Hinata's gentle nature. Eventually, they realize their feelings and get married, with Itachi vowing to protect Hinata forever.
One possible plot twist could be that their marriage causes a rift in the ninja world. Some might oppose it due to Itachi's past actions. Another could be that they discover a new power that comes with their union, which is crucial in saving the world from a new threat. And perhaps they have to deal with family issues, like Naruto trying to make Itachi feel welcome in Konoha despite his past.
For Itachi, he could become more open and less brooding. Hinata's love and support might make him feel like he can finally let go of some of his past burdens. For Hinata, she could gain more confidence in herself. Being with Itachi, who is highly skilled, gives her the motivation to train harder and become a stronger ninja. Also, she might become more assertive in dealing with clan matters, especially when it comes to any opposition to their relationship.
One possible plot could be that Itachi, after his death, is somehow reincarnated or brought back in a different form. Hinata discovers the baby which has a strange connection to Itachi. She decides to take care of the baby, believing it's a sign from the heavens. As the baby grows, it starts to show Itachi's skills and wisdom, and Hinata has to protect the baby from those who might want to use its powers for evil.
In a fanfic of their marriage, Naruto and Hinata would face challenges too. Naruto is often very busy with his Hokage duties. But Hinata would be understanding. She would manage the household while Naruto is away. When they are together, they would probably train together to keep their ninja skills sharp. Their marriage would be a symbol of unity in the village, and they would be an inspiration for the younger generations of ninjas.
Well, perhaps in a fanfiction, Sasuke could be on a mission and get injured. Hinata, who is also on the same mission (for some reason), takes care of him. This act of kindness makes Sasuke see her in a new light. They start to bond over their shared experiences and their understanding of the ninja world. Eventually, they fall in love and marry. Their married life could then be about protecting the village together and dealing with any threats that come their way.
One possible plot twist could be that an old enemy resurfaces just as they are about to get engaged. This enemy might try to disrupt their relationship by spreading false rumors about Naruto, like he has some hidden dark power that could endanger Hinata. Another twist could be that Hinata's family has some ancient clan secret that surfaces and creates a rift between them and Naruto's side. Maybe the secret is related to a power that the Hyuga clan once had and lost, and they fear Naruto might be involved in its re - emergence in a negative way.
One possible plot could be that Naruto and Hinata are overjoyed at the news of the pregnancy. Hinata starts preparing the nursery with Naruto's help, painting it in soft colors. Naruto, being the Hokage, has to balance his duties with taking care of his pregnant wife. He often comes home with little gifts for the baby, like a tiny Hokage - style hat. And Hinata spends her days knitting baby clothes and reading books on parenting, all while feeling the baby's kicks and sharing those precious moments with Naruto.
One possible plot could be that Naruto, being from his ninja world, somehow gets transported to Erza's world. They meet by chance during a battle where they initially mistake each other for enemies. But as they start to understand each other's powers and motives, they develop a mutual respect. Eventually, this respect turns into love and they decide to get married. Their wedding could be a grand affair with Naruto's friends from Konoha and Erza's guildmates coming together to celebrate.
One possible plot could be that Ash and Lana start off as friends during their Pokemon adventures. As they grow closer, they realize their feelings for each other. They might face some challenges like Ash's constant traveling for Pokemon battles. But in the end, they decide to get married. Their Pokemon friends could also play a big role in the celebration, with Pikachu and Popplio being the ring bearers perhaps.
One possible plot could be their struggle to gain acceptance from their families and the different vampire and werewolf communities. Jacob might face opposition from his pack initially as marrying a half - vampire is unheard of in their traditions. Renesmee, on the other hand, may have to deal with the over - protectiveness of her vampire family who are cautious about her union with a werewolf. As they navigate these challenges, their love for each other deepens and they find ways to bridge the gaps between their two worlds.
