I'm not sure about a specific 'itachi x hinata x sasuke fanfic' to recommend. You could try searching on fanfiction websites like Archive of Our Own. They usually have a wide variety of fanfics, and you might be able to find one that involves this particular pairing.
Maybe in the fanfic, Itachi returns from the dead in some sort of magical or mysterious way. Sasuke is initially conflicted about his brother's return, and Hinata, with her kind heart, tries to bridge the gap between the two Uchiha brothers. Along the way, feelings start to develop between all three characters, and they must navigate their new relationships while also dealing with threats to the Hidden Leaf Village.
One great 'itachi x sasuke x naruto fanfic' is 'The Bonds Beyond'. It focuses on the complex relationships between the three characters. It shows how their past experiences shape their interactions in an alternate universe.
I really like 'The Redemption of Itachi in Sasuke's Eyes'. This fanfic shows how Sasuke's perception of Itachi changes over time. It has some amazing character development and it also weaves in some great action scenes that are related to their relationship.
They could face challenges in terms of trust. Given Itachi's past of secrecy and Hinata's insecurities, it might take time for them to fully trust each other. There may also be external threats that target their relationship because of the power and influence their combined clans hold. For instance, enemy ninja might try to drive a wedge between them. And on a personal level, Hinata may struggle to keep up with Itachi's high - level ninja skills in some situations, which could lead to self - doubt and potential friction in their marriage.
Another theme is redemption. Itachi has a lot of actions in his past that need redemption, and in these fanfics, his relationship with Sasuke and Naruto can be a part of that journey. Like, his actions towards Sasuke are re - evaluated in the context of a new understanding among the three.
The theme of sacrifice also often appears. Itachi sacrificed a great deal for Sasuke and the village. Fanfics might expand on this, like showing how Sasuke comes to fully understand and appreciate Itachi's sacrifices, and how that understanding changes their relationship.
No, writing sexual fanfics about characters, especially when it involves incestuous themes as Itachi and Sasuke are brothers in the Naruto series, is inappropriate and goes against ethical and moral standards. It also violates the respect for the original work and its characters.
Love triangles also appear quite often. Given Hinata's feelings for Naruto and the complex relationship between Naruto and Sasuke, writers play around with the idea of how these relationships can develop in different ways, adding a touch of romance and drama to the stories.
I really like 'The Trio's Destiny'. It starts with a strange event that binds Naruto, Hinata, and Sasuke together. As the story progresses, their individual goals start to blend with their newfound connection. It shows how their different personalities can either clash or complement each other in a really interesting way.
