Maybe he realizes the exam is too dangerous or he discovers some unfairness in it. In the original Naruto story, Naruto has faced many difficulties and moral dilemmas during the Chunin Exam. So in the fanfiction, similar situations might push him to quit.
One possible fanfiction could be about Sakura showing off her improved medical ninjutsu skills during the Chunin Exam. She might use her skills to quickly heal her teammates during battles, surprising everyone with her growth.

One possible fanfic could be about Naruto and Temari teaming up during the Chunin Exam in unexpected ways. Maybe Naruto helps Temari when she's in a tough situation against an opponent she underestimated. They could form an alliance that surprises everyone.
Naruto would likely become more self - reliant. As a ronin, he doesn't have the support of a village. So during the Chunin Exam, he has to trust his own instincts and skills more. He may also become more cautious as he realizes he can't always count on backup.
In a fanfic, on Chunin Exam Day, there could be intense battles. Young ninjas might show off their new and improved jutsu. There could be unexpected alliances formed between rival teams as they face a common and tough enemy. Also, there might be some back - story revelations about the characters, like their hidden motives or past traumas that drive them during the exam.
Typically, the young ninja trainees like Naruto, Sasuke, and Sakura could be the protagonists on Chunin Exam Day in a fanfic. They are the main characters in the original series and are likely to play important roles in any fan - created story about the exam.
In a fanfiction, Sakura could be in a fight during the Chunin Exam where she faces a much stronger opponent. However, instead of relying on brute force, she uses her intelligence.

Well, in this fanfiction, their daughter may have some internal struggles too. On one hand, she wants to make her parents proud in the Chunin exam. On the other, she wants to be recognized for her own merits. So she might try to avoid using her parents' well - known techniques at first. However, as the exam gets tougher, she realizes that she can put her own spin on her parents' skills and use them to her advantage, like using a new form of sand - infused medical jutsu.
They could have a battle where Naruto discovers a new way to counter Temari's wind - based attacks. For instance, he might use his shadow clones in a creative way to disrupt the flow of her attacks.
