Honestly, I'm usually skeptical of that specific premise because the dynamic is more complicated than pure resentment. Naruto feeling overlooked could make sense, but I've seen too many stories where it devolves into simplistic Kakashi-bashing. That said, 'Ghost' by mapplepie on FFN is a standout because it treats the conflict as a symptom of a larger breakdown in the team post-Sasuke's defection. Naruto's anger is cold and directed inward, and Kakashi's failure isn't painted as malice but as a flawed teacher struggling with his own ghosts. The training neglect is the catalyst, but the story becomes about how they navigate mutual disappointment, not just Naruto getting a power-up from someone else.
For a darker take, 'Naruto: Ouroboros' (I read it on AO3) explores it well. Here, Naruto's bitterness stems from Kakashi prioritizing Sasuke's sharingan potential over everything else, which feels very in-character given the world's biases. Naruto doesn't just hate Kakashi; he internalizes the message that he's inherently less worthy of attention, which fuels a much grimmer development path. The writing can be uneven, but the emotional core of that betrayal rings true. It's less about training and more about a foundational mentorship failing when it was needed most.
