What is the meaning behind Hinata calling Naruto "Nee-sama"?

In the anime and manga series "Naruto," Hinata Hyuga refers to Naruto Uzumaki as "Nee-sama" as a term of endearment and respect. "Nee-sama" is a Japanese honorific that means "older sister," but is often used by female characters towards male characters they admire or look up to. In Hinata's case, she admires and respects Naruto for his perseverance, determination, and kind heart, which she lacks in herself. By calling him "Nee-sama," Hinata is showing her affection and admiration for Naruto.
