If Naruto is a brother in this fanfiction, it would change the dynamic quite a bit. He might be more bossy in a brotherly way, making sure his 'siblings' in Team 7 are training hard and staying out of trouble. His relationship with Sasuke, for example, would become less of a rivalry and more of a brotherly competition to make each other better. And with Sakura, he could be more over - protective, which might annoy her at times but also make her feel secure.
Naruto might also be determined to change his brother's mind. He would keep showing his good side, like his kindness and his strong will to protect the village. He could think that by being a better person, his brother will eventually stop hating him. He may even go through some tough training to prove himself not only to his brother but also to the whole village. And in the process, he may face a lot of difficulties and rejections from his brother, but he won't give up easily.
Well, often in fanfiction, Naruto's love for his brother can be depicted as a deep emotional bond. This might be different from the relationships he has in the original story. Maybe he has a brother who is in a difficult situation, and Naruto's love drives him to fight against all odds to save his brother. It could be a story full of heart - warming moments and intense emotions.

I recommend the novel " Demon of Breaking the Marriage at the Beginning and Helping His Brother ". In the story, the older brother was worried about his younger brother being alone because of the burns, so he found a wife. The younger brother married in his brother's name for the sake of his older brother. The plot of this novel is very similar to what you described. I hope you will like it.
