In such a fanfiction, one possible plot development could be that Naruto sacrifices himself during a major battle against an extremely powerful enemy. Maybe an enemy that has the power to destroy the entire Hidden Leaf Village. Naruto, being the hero he is, steps in to protect Hinata and in the process, takes a fatal blow meant for her. This would lead to great sorrow among the villagers, especially Hinata who would be heartbroken. She might then vow to carry on Naruto's will and protect the village in his memory.
Perhaps Naruto and Hinata are on a mission together. They get ambushed by a group of rogue ninjas with some new, unknown and deadly jutsu. Naruto, seeing Hinata in immediate danger, uses his own body as a shield. His death would then trigger a series of events in the village. The villagers might start to question their security measures. Hinata, on the other hand, could be so stricken with grief that she isolates herself at first, but then slowly realizes she needs to be strong for Naruto's sake and for the village.
