In some fanfics, it could be that Naruto is facing an identity crisis which is slowly breaking his mind. Ino, being a member of Team 10 and having some knowledge of Naruto, stumbles upon his situation. She might then team up with other characters, like Shikamaru or Choji, to figure out a way to bring Naruto back to his normal self. The plot could also involve Ino delving into Naruto's memories to understand what has led to his broken mind and then using that knowledge to mend his psychological state.
