this is amazing. Naruto couldn't be that child like and happy with the life he had

this really is a wonderful story and I think you've done a good job delving into Naruto's head. there is no way he'd be so happy and optimistic after the life he's had and this explains his reality and his personality

Interesting though I always thought of Naruto's canon personality to be too loud and moronic for him to be effectivly hiding anything.
