? I don't get it. Don't most stories generally need a conflict for the main characters to work towards and solve? The conflict here is past trauma and ill-relations.
Without that established, when (if) the story reaches its climax, would it not feel like a different story was sold to us?
Imagine if Naruto started when Naruto became a genin and not as a shunned kid desperate for acknowledgement. Would the end of the Pain arc hit as hard?
