Well, Naruto in fanfiction often shows his emotions verbally. He's not one to hold his tongue. So, he might passionately declare his love for Hinata in a really sappy and over - the - top way that makes everyone around him roll their eyes but also feel the warmth of his emotions. Also, when he's sad, he could be shown as isolating himself from the group, which is a clear sign of his inner turmoil.
Perhaps in the fanfiction, Naruto accepts his dark emotions with the help of his friends. His friends, like Sasuke, Sakura, and Kakashi, might encourage him to face his inner demons. They tell him that it's okay to have dark emotions and that everyone has them. Naruto then starts to accept his own, knowing that he doesn't have to face them alone. His friends' support gives him the confidence to embrace his whole self, including the darker aspects of his emotions.
Well, he would probably become much more cold and detached. He might lose his drive to protect his friends and the village in the same passionate way. His actions would be more mechanical, lacking the warmth and empathy that used to be his trademarks.
In some fanfictions, Naruto might show his love for his sister by protecting her at all costs. For example, he would stand in front of any danger that comes her way, just like how he protects his friends in the original story.
He often keeps a close eye on Naruto. In many fanfictions, Kakashi will be secretly observing Naruto during his training or missions, just to make sure he doesn't get into too much trouble.
Well, it could really mess things up. Naruto's relationships are often based on his big heart and passion. If he seals his emotions, his interactions would become more mechanical. People who love him for his energy, like Iruka, would find it hard to connect with this new, emotionless Naruto. He'd be like a different person, and his relationships would have to start from scratch in a way.
His relationships would be in turmoil. Naruto not being aware of his emotions is like sailing a ship without a compass. In his relationships, especially with those close to him, he'd be lost. He might do things that seem out of character because he's not in touch with his feelings. For instance, when it comes to his sensei, he may not be able to show the proper respect or gratitude because he doesn't understand the emotions behind those concepts. His friends would constantly be trying to figure out what's wrong with him, and he'd be equally confused, leading to a lot of strife in his relationships.
Well, Naruto is known for his positive energy. In this fanfiction, he could show his love for his siblings by bringing that positive energy into their lives. He would cheer them up when they are down, encourage them when they face difficulties. He might also cook for them or do some small but meaningful things, like helping them with their training or just listening to their problems.
In fanfiction, Naruto might show his love for his mother through his memories. He could constantly recall the little time he had with her. For example, he might remember any advice or lullabies she gave him. These memories could fuel his actions, like when he faces difficulties, he might think about how his mother would want him to be strong and persevere.
In some fanfictions, Naruto shows his protectiveness by getting extremely angry when someone badmouths Sakura. He won't tolerate any disrespect towards her and will quickly defend her honor. He might also use his influence in the village to make sure Sakura is always safe and well - cared for.
One of the ways Naruto is like his father is in his self - sacrifice. Minato sacrificed himself to save the village and Naruto has on several occasions put himself in harm's way for the greater good. He doesn't hesitate to give his all, whether it's against powerful enemies or for the safety of his comrades, just like Minato did.
