Her obsession can also shape the relationship - building aspect of the plot. It can create a sort of push - and - pull dynamic. Maybe Naruto is initially oblivious to her feelings, and her attempts to get closer because of her obsession lead to comical or heart - warming moments. As the story progresses, their relationship can evolve based on how she expresses and manages her obsession, which is a major part of the overall plot.
Well, it can drive the plot in many ways. For instance, if Hinata is obsessed with Naruto, she might make decisions based on her feelings for him. This could lead to her getting involved in dangerous situations that Naruto is in, just to be close to him or to protect him. So, her obsession becomes a key factor in creating action and tension in the story.
