AN: This is Uchihacest. I repeat this is Uchihacest. So if you don't want to read of brother x brother relationship, press the back button immediately. Also this is AU (alternate universe), so the characters will be OOC. I guess that's all the warning for now. If you don't mind Uchihachest and wishes to read the story, I hope you like it. Thank you!

**AN (03/04/2019): I'm rewriting this story. Most parts of this story will remain unchanged but there will be a lot of changes too. Thank you.

Chapter 1: Once Upon A Time... No

Once upon a time, it's such a common phrase to stumble upon when starting to read a fairy tale. Even though this story is nothing like a fairy tale, let's begin it like that anyway.

So, once upon a time in a huge mansion called 'Amaterasu', lived a boy named Itachi Uchiha. At that time, he was only four years old. The boy was very cute, owning coal black eyes and equally black hair. His skin was soft, fair and flawless. There were two long pronounced tear-troughs on the child's face. But they only enhanced the boy's beauty. It wouldn't be wrong to compare Itachi with a prince. The boy's aura certainly was of a prince and so was his lifestyle.

Itachi was born into the famous Uchiha family. The Uchiha family was one of the top business families of Konoha. Konoha was the base of many multi-million dollar companies. Therefore, to be on top with only a handful rivals was really something. The Uchihas owned Sharingan Corp. which needless to say was among the most successful and prominent companies. The Uchiha family didn't have very many members like the Hyuga family. However, every single member of the Uchiha family was a force to be reckoned with.

The head of the family and also the current CEO of Sharingan Corp. was Madara Uchiha. In the corporate world of Konoha, no other man was a more cunning businessman than Madara. No one messed with him or the Uchiha family unless they had a death wish. He was both ruthless and at times reckless. He was both respected and feared. Madara's power was unquestionable. The man did have some redeeming qualities though. One of them being the fact that he loved his family. Ferociously so. He was protective of each member and for that the rest of the Uchihas respected him and relied on him without any doubt. Despite being an alleged ladies man, Madara never settled down. He didn't get married nor had any kid of his own. He did however adopted someone. That someone being Obito Uchiha. He was said to be the son of Madara's cousin. However, there were plenty of rumors about it. One of them was that Obito was actually Madara's bastard child from one of his many affairs. Though the official story was that Obito's parents died in a car crash. He was being raised by his grandmother afterwards but even she died after sometime, leaving Obito completely alone until Madara took him in. The scar on Obito's face that he got in that accident made the story more believable to the public. And that was all that mattered. After all for any business family, specially one with a reputation like the Uchihas, having a clean image in the media was everything.

The second important person of this family was Izuna Uchiha. He was Madara's younger brother. There was a saying that if Madara listened to anyone, it was his brother Izuna. Izuna was the only one who could control Madara when the man was about to take something too far. Izuna didn't have this power for nothing though. He was after all very devoted to his older brother. If someone threatened Madara, that person would find himself dealing with Izuna first. Despite possessing softness in behavior and calm demeanor and overall seeming more approachable than Madara, if something pissed Izuna off, he could become a real nightmare. When Madara wanted to destroy someone, he'd put on a great show of it. Making him more fearful to people. But that wasn't Izuna's style. He always worked subtly. His enemies never know what was going on, until it was too late. Making him more dangerous than Madara at times. When Sharingan Corp. was still climbing the ladder, it was Izuna's intelligence that kept other corporations from stomping on them. Even now, it was thanks to his brilliant mind, that Sharingan Corp. was thriving in such a competitive industry.

Izuna got married right after his university graduation. The girl's name was Momo. They started dating since Izuna got into the university and decided to get married after their graduation. They had a good relationship during their studying years, but unfortunately, after marriage, the more Momo started to get involved in the family matters, the less she could handle it. After all the Uchihas were involved in plenty of questionable things in order to stay on top. They did have a son together, named Shishui Uchiha but even that couldn't save their marriage. Izuna and Momo got divorced when Shishui was barely five years old. Momo did fight for her son's custody but who could ever win against the Uchihas.

'Uchihas stayed together' that was what Izuna said to her. And Shishui was undoubtedly an Uchiha. Momo wasn't an Uchiha, therefore she could leave but not Shishui. The boy belonged with them. Momo was bitter about it for a while but for the sake of her son, she established a formal relation with Izuna. At least that way she got to meet her son once in a while. After Momo, Izuna didn't get into any other serious relationship. He devoted his time to taking care of little Shishui and of course the business.

The third, and the most loved member of this family was their little sister Mikoto. Unlike her brothers, she was a loving and kind hearted person. Mikoto contrasted her brothers greatly but at the same time balanced them as well. It was only with Mikoto, that both Madara and Izuna could let their guards down. Not having to think carefully before saying anything. With her, they could show their flaws and weaknesses without hesitation. All in all, Mikoto was their safe heaven. Their beloved little sister. Mikoto loved her brothers too. But she also kept them grounded. She was the only person who could get away with defying Madara. Not that, that happened a lot but there were a few moments here and there. Mikoto even got to scold them whenever she thought her brothers were taking things too far. Because Mikoto was their little sister, both Madara and Izuna wanted to spoil her rotten but she never let them. Instead she kept them in check. Mikoto was a mature person since she was very young.

Madara always feared that someone would take advantage or hurt Mikoto since she was so kind hearted. It sometimes made him overprotected of her. Therefore, when Mikoto expressed her desire to marry Fugaku Uchiha, a man who was a distant relative of theirs, Madara had immediately said no. Thinking that Fugaku must be after their money and status. Not believing for a second that the man truly loved his sister. That was the first time, Mikoto actually defied her brothers and against their wish, she married Fugaku. Both Madara and Izuna stayed angry with Mikoto for sometime. But who were they kidding. As soon as they heard that Mikoto was pregnant with her first born, they couldn't stop themselves. The siblings reunited forgetting all their anger. Not to mention, when Madara and Izuna gave Fugaku a chance they found out that the man really did love their sister. Fugaku wasn't a man of many words, and overall he was a serious person but his heart was in the right place. That was what had attracted Mikoto to him in the first place.

Soon, Fugaku was not only approved of as Mikoto's husband but accepted into the family business as well. Though Fugaku was in the police force but he proved to have a good sense of business as well. His intelligence, intuitiveness, and sense of judging a person's character and intentions came in very handy for the Uchiha Corp. To put it shortly, Fugaku fit right in. However, his sense of right and wrong, kept him from being directly involved with the shady parts of the business. But once in a while he had to dirty his hands too.

The birth of Itachi Uchiha would forever be something special to the entire Uchiha family. He was the first born son of beloved Mikoto. Madara and Izuna's love for their sister, only increased more for their nephew. Both of them celebrated Itachi's birth for a whole week. Throwing parties, giving donations to different social organizations, doing press conferences to let the entire city know of their new born nephew and etc etc. As soon as Itachi started to grow up, the family started to realize he was no ordinary child. Even as a mere child of four years old, Itachi was quiet, observant, he learned things quickly and behaved very maturely. Mikoto didn't remember Itachi ever crying his lungs out or throwing an anger tantrum or unnecessarily seek his parents' attention. Itachi never asked for toys but he would be accepting and thankful if anyone gave him anything. Itachi was always more interested in observing people rather than play with toys. Mikoto also didn't remember Itachi ever getting excited about something. That was until she told him one day that he was going to be a big brother.

The four year old Itachi ran inside the mansion. He had gone out with his father early in the morning. Itachi looked a little impatient as he searched for something; or perhaps someone. The boy spotted a house maid nearby, dusting off a picture frame. Itachi ran up to her and asked-

"Where is mother?" Itachi sounded perfectly polite but impatient nonetheless.

"She's in the garden, Itachi-sama." The maid replied bowing her head a little. Itachi was used to of their employees addressing him with honorifics. Apparently having Uchiha in the name automatically demanded respect whether it was earned or not.

"Thank you" said Itachi before running off towards the garden to find his mother. Mikoto was indeed in the garden and she appeared to be heavily pregnant as well.

"Mother!" Itachi exclaimed as he ran up to her. One glance at the boy and the woman and anyone could tell that they were related. Itachi resembled his mother in many ways. He definitely got Mikoto's beauty.

"Welcome home Itachi." Mikoto said to her beloved son affectionately. She wrapped her arms around and embraced the boy.

"How was your day dear? Did you enjoy going to your father's office?" Mikoto asked wanting to hear about her son's day.

"Yes mother, I had fun. Uncle Madara and Uncle Izuna were very happy to see me. Uncle Izuna even took me out to eat dango. They said they would visit here soon and that they miss you" said Itachi. Madara and Izuna didn't live very far but their mansion Susanoo was closer to the office, making it more convenient for them. They did try to visit Mikoto as much as they could though. But sometimes Madara and Izuna wouldn't get a chance to visit for weeks due to having too much work to do.

"I look forward to it. I miss them too" said Mikoto with a smile.

"They've been so busy lately; your father too." She said this a little sadly.

"Father says it's important to work hard to achieve success and work harder to keep that success" said Itachi a little too thoughtfully for a kid of his age.

"That's right dear but remember you should also have time for your family too. Business is important but so are the loved ones." Mikoto advised wisely and Itachi nodded his head accepting that advise. After that Itachi looked at the baby bump and smiled happily. He leaned in and put his ear on the bump while caressing it affectionately. Mikoto's heart warmed up seeing the happiness on her son's face. Itachi rarely showed his emotions, therefore Mikoto cherished such moments with all her heart.

"When will my otouto come out mother?" Itachi asked innocently. But it was clear from his voice that he couldn't wait for the baby to be born.

"He'll be born this summer, if it's really a boy" said Mikoto with an amused smile. She and Fugaku both agreed not to do any test to find out the baby's gender. They wanted it to be a surprise. But somehow Itachi was certain about having a baby brother.

"It is a boy." Itachi insisted. "It's my little brother."

"Well, I hope it's your little brother but don't be too disappointed if it's a little sister, okay. You'll be a big brother either way."

"I won't be disappointed. I already know I'm going to have a brother." Mikoto could only shake her head at the boy's persistence and smiled affectionately.

"You already love him so much, don't you Itachi? You're going to be a very good big brother." She said, knowing it to be true in her heart.

"I will be" said Itachi with determination in his voice as if making a promise here. But then he suddenly got a little worried.

"But mother, will he love me too?" Itachi asked with a hidden anxiousness in his voice. As if it would crush him if his yet to be born little brother didn't love him back. Mikoto smiled at her son in an assuring gesture.

"Of course he will love you Itachi. You'll be his big brother. There will be a bond between you two that no one can break." The answer clearly made the boy happy as he grinned happily.

"I can't wait for my otouto to be born." Itachi admitted out loud making Mikoto laugh joyfully.

"I know dear. Neither can I."

At that time, neither Mikoto nor Itachi could have known just how much the yet to be born child was going to love his big brother. Only time could tell. And it did.
