Another way is through self - reflection. Naruto could have moments where he realizes that his fear of touch is holding him back. He could then start to take small steps to overcome it on his own, like touching things or animals first. This would show his growth as he faces his fear.
The author could also use flashbacks. By showing Naruto's past experiences that led to his fear of touch, and then showing him gradually overcoming those memories and the associated fear. For example, if he had a bad experience with a bully as a child, he could face a similar situation in the fanfiction but react differently this time, indicating growth.
The author could start by introducing a character who gradually earns Naruto's trust. This character could start with small, non - threatening touches like a gentle pat on the shoulder. Over time, as Naruto gets more comfortable, the touches could become more affectionate.
One possible reason could be some past trauma. Maybe he had a bad experience during a battle or an encounter that made him associate touch with danger. For example, if he was once grabbed forcefully by an enemy during a fight and it led to a near - death experience, that could make him scared of touch.
One possible reason could be his past traumas. He grew up lonely and was often shunned by the villagers. This lack of positive human contact in his early years might have made him wary of touch in fanfiction. For example, the constant glares and cold shoulders from the villagers could have made him unaccustomed to friendly or affectionate touches, leading to fear.
It can create misunderstandings. For instance, his friends might think he doesn't like them if he recoils from their touches. His romantic relationships could also be affected. If he's in love with someone in the fanfiction, his fear of touch would make it difficult for him to show physical affection, which is an important part of a romantic relationship.
In this fanfiction, Naruto's fear of Kushina at night can show his vulnerability. Despite being a strong ninja, he has this fear which makes him more human. It can also be a way to explore his relationship with his mother. His fear might lead to him trying to understand more about Kushina and their family history.
It can make his relationships more intense. For example, in his friendships, he might be overly eager for hugs or physical contact from his friends like Sasuke or Sakura. This could initially surprise them but then lead to a deeper bond as they understand his need. In romantic relationships in the fanfiction, his touch - starved nature might make him more clingy at first, but also very loving and devoted once he feels secure in the relationship.
One way is to show Naruto having nightmares about thunder. These nightmares could be so vivid that they start to affect his daily life. He could become more jumpy during thunderstorms, and this could lead to him making mistakes in his ninja training or missions. As the story progresses, his friends could help him deal with these issues.
One possible reason could be that his sister has some special or unknown powers that Naruto doesn't understand. For example, if she has a very unpredictable and potentially dangerous kekkei genkai. Another reason might be that she has a very strong and intimidating personality, which makes Naruto feel small and scared in her presence.
One way is to put Naruto in situations where his lack of understanding of emotions causes problems. This could lead to conflicts with his friends or allies. As he tries to resolve these issues, he begins to figure out how emotions work. For instance, if he accidentally offends someone because he doesn't get their emotional state, he has to make amends and in the process, learn about that particular emotion.
In a battle scenario, his touch sensitivity could be both a weakness and a strength. An enemy might try to use it against him by making unexpected touches during combat. But on the other hand, Naruto could use his heightened sense of touch to detect hidden attacks or sense the presence of enemies more acutely. This duality can add a lot of excitement and unpredictability to the battle scenes in the fanfiction.
One possible reason could be his past traumas. Harry has faced many dangerous and life - threatening situations. For example, the numerous attacks from Voldemort and his Death Eaters. These experiences might have made him overly cautious and averse to physical touch as it could potentially be from an enemy. Also, his upbringing in the Dursley's household wasn't exactly warm and fuzzy. The lack of positive physical contact there could have contributed to this fear.
