In some fanfictions, it could be Hinata. They have a strong connection in the original series, and it would be a natural progression for them to get married and start a family.

One great 'Naruto Wife' fanfic is 'A New Beginning'. It explores an alternate universe where Naruto's wife is not Hinata but a new character. The story focuses on how this new relationship affects the entire Hidden Leaf Village and Naruto's journey as a husband and a leader. It has great character development and an interesting plot that keeps you hooked.
Hinata could be a likely candidate in such a fanfiction. Since she is Naruto's real - life wife in the original series. Writers might twist their relationship in fanfiction and create a scenario where she betrays him. Maybe due to some family pressure or a misunderstanding that gets out of hand.
One aspect to consider in this Naruto and Haku fanfiction where she's his wife is the cultural implications within the Naruto universe. In the ninja world, marriage is not just a union of two people but also has implications for clans and villages. Naruto being a prominent figure in Konoha and Haku having her own background (even though she was initially from the Land of Water). Their marriage could be a symbol of unity between different regions or even a way to bridge the gap between different ninja ideologies.
A good 'Naruto Wife' fanfic should have a well - developed relationship. For example, it should show how the two characters fall in love, not just suddenly put them together.

His wife could be Hinata. In the original series, there were hints of their relationship. Hinata has always admired Naruto and they would make a great couple. She is a strong and kind - hearted ninja from Konoha, which would make for an interesting dynamic when Naruto returns with her as his wife.
In such a fanfic, Naruto might initially be in a state of deep shock and denial. He could isolate himself from his friends and the village for a while, brooding over the loss and constantly replaying memories of his wife in his mind.
