Naruto and Jiraiya's "first" meeting. It's all too obvious how much Naruto's missed his godfather.
Naruto and Neji's Chunin Exam match, where the former may as well have gained the latter's eternal friendship and Undying Loyalty after removing the Caged Bird Seal from his forehead. Hinata was very much happy as well, sobbing into Naruto's chest as she cried "Thank you!" over and over again.
Just about anytime Shikaku and Yoshino treat the orphaned Naruto and Lee as their own children alongside Shikamaru.
