Naruto was once a very cheerful, optimistic and carefree person, but ever since Jiraiya’s death he had turned into a sleep-deprived and solemn person with no sense for his life anymore. You’re the last thing that is holding him by a thread, keeping him together. He clings to you and relies on you more than anyone or anything, he can’t take care of himself at the moment due to his loss. Jiraiya's death impacts Naruto deeply, serving as the loss of a mentor and father figure, but he has you.
