Some popular themes include the exploration of their brotherly bond at a younger age. It could be about Sasuke looking up to Itachi in a more innocent time before all the tragedy. Another theme might be their training together, with Sasuke eager to learn from his older brother. Also, the family dynamic within the Uchiha clan when they were younger can be a focus, like how Itachi's actions even then were subtly influenced by the clan's expectations.
Maybe Itachi gets sick. Then Sasuke has to take care of him, getting medicine and staying by his bedside. He'd worry about Itachi's health and do everything he can to make him better.
Writers often vary in how they portray the relationship. One way is through their communication. In some fanfictions, they have more open and friendly conversations as kids, while in the original story, there are always undertones of mystery. Another difference could be in their physical interactions. For example, some writers might have them hugging more often as young brothers, showing a closer emotional bond. Also, the level of trust can be depicted differently. In some fan works, Sasuke trusts Itachi completely from the start, which is a contrast to the real story where trust is gradually eroded.
Sasuke might develop more patience. Since Itachi is younger in this fanfiction, Sasuke has to be more understanding. He can't be as impulsive as he usually is. For example, he might have to learn to soothe Itachi when he's scared or upset, which helps Sasuke grow into a more empathetic person.
😋I recommend two novels to you, both of which are Naruto Doujin novels that meet your needs. The main character transmigrated into Sasuke's relative. The first book was " Return to Naruto with the League of Legends system." The main character Fang Wei became Sasuke's younger brother after transmigrating. He also brought the League of Legends system and used it to leave behind one legend after another in the Naruto world. The second book was " Naruto: Illusion God ". The main character, Takiyichi, became a member of the Uchiha family and specialized in illusions to save the Uchiha family in the late stage of the second year. I hope you like my recommendation.😗
I can't provide Naruto, Tami novels because this kind of content might not be suitable for everyone. I can recommend other types of novels for you. You can choose according to your needs. If you have any other questions, please feel free to let me know.
😋I recommend " Uchiha no Uchiha's Red Flame " to you. This novel was written by the author, Mr. Ear Hole. It tells the story of a Shushan disciple named Lu Chiyan who was accidentally reincarnated to the Naruto Continent and became the twin brother of Uchiha Sasuke, thus creating a new life path. In the novel, the male protagonist, Chi Yan, might not be completely cold, but his personality was indeed relatively calm. He had his own beliefs and principles, and was able to calmly face the challenges of reality and welcome new challenges. I hope you like this calm and determined male lead.😗
Yes, there might be such fanfics out there. In the Naruto fandom, with a large number of fans creating various types of stories, it's possible that some would write a story where Naruto destroys Sasuke in a way that could be seen as Sasuke - bashing. However, these kinds of fanfics may not be in line with the overall spirit of the original work which focuses on their complex relationship and growth.
I recommend two novels, Ugly Woman Coming Out of the Mountain and Dazzling Jin. " The Ugly Woman Coming Out of the Mountain " was about a princess who was framed and disguised as an ugly woman to mingle in the Divine Mountain, where she slowly developed her business empire. On the other hand," Dazzling Beauty " was about an unruly princess who was forced to marry into the royal family. She was kidnapped at the wedding and was later replaced by a servant girl. The princess then went all the way to the other country with difficulty and developed a sentimental relationship with the cold prince. I hope you like my recommendation. Muah!
😋I recommend you a novel,'Tong Hua blooms in spring'. The female protagonist's sister is the man's sister, and she's mute. I hope you like my recommendation, Mwah ~😗
