~Sei Nii-sama~

For the first seven years of his life, Seijuro is an only child. He was spoiled, he was given all the attention and mostly, he had his parents love solely to himself.

Until the day he turned eight...and everything changed.

His little brother came into their lives, and for the first time in his life, Seijuro had to share. He's no longer just the center of attention and their parent's love is no longer just his.

It's no longer just him, it's now them.

And Seijuro, at the age of eight found out what jealousy is. He did not understand yet, why does he have to give? Why does he have to share? Why can't everything just be the same?

"Sei come look at your brother. Isn't he just the cutest"

"I don't want to father"

"I'm sorry, Sei but it's Tetsuya's monthly check-up so we can't go to the mall today"

"But mother, you promised. Why does it always have to be him?"

"Seijuro, don't be too loud or you'll wake your brother up."

"Sei, don't show that scary face to your little brother"

"Sei, your brother..."

"Tetsuya is such an angel"

"Tetsuya..."

"Tetsuya..."

"But mother, father it's always Tetsuya. Don't you guys love me anymore?"Two pairs of eyes widened upon hearing those words and Shiori immediately told her son to take a seat. The young boy complied.

"We give more attention to Tetsuya because your brother is still too small and fragile and we have to take good care of him. When you were just as small, we did the same thing. Honey we're sorry if you feel like we've been rejecting you this past weeks but listen to me, not just because we give him more attention now doesn't mean we love you any less"

"Your mother is right, You will always be our precious baby boy even if Tetsuya is here now. You understand that, right?"

A small nod.

"What about we all go out this weekend? You wanted to go see the circus, hm?"Shiori asked her firstborn. The boy's eyes sparkled with the idea.

"Really?"

"Yes, we'll all go but Seijuro had to promise something" The young Akashi gave his parents a questioning look.

"Can Seijuro try to be a great big brother?" The young redhead looked at his younger brother sleeping soundly on the crib.

"...I'll try"

"That's our boy" Masaomi smiled, ruffling his son's hair. Seijuro kept his eyes on his younger brother, maybe it wouldn't hurt to try.

A young eight year old happily played with his lego collection, making funny childish sounds as he ran all around the house and giggling from time to time.

"waaahhh!"

Seijuro stopped on his tracks. It looks like his brother is crying, again. It was loud and irritating and the redhead found himself feeling slightly annoyed. Are babies really that loud?

Where is their mom, anyway? Seijuro frowned remembering that she's currently taking a shower downstairs and won't be done for at least another twenty minutes.

None of the maids are available as it was their off day and their father is still currently at work.

"Waaaaahhhh!"

Seijuro opened the door towards the nursery. Looks like he had no choice but to make Tetsuya stop.

"Shut up!" Seijuro glared at his brother. "You're too loud" He pointed rudely, commanding his baby brother to stop crying and to his satisfaction, Tetsuya did stop crying. Seijuro smirked, at least he's listening to him.

...and then Tetsuya giggled. Seijuro blinked. "Hey! Why are you giggling?" His brother can't answer him of course.

"Stop giggling!" Tetsuya's giggles became louder.

"Are you laughing at me?"

Tetsuya laughed. Seijuro twitched. Of course, he is. The older boy moved his hand, attempting to place a finger in an attempt to make Tetsuya stop. No one laughs at Seijuro! No one!

To his horror, Tetsuya's tiny hands had managed to caught Seijuro's fingers and even attempted to put the finger inside his mouth. Seijuro tried pulling his finger away but his brother's hold is just too tight. It didn't help when Tetsuya had managed to nibble on his finger. Seijuro's eyes widened with disgust. Saliva! ew!

"Tetsuya, let go" Seijuro demanded, still trying to free his finger. Tetsuya, not understanding a word, however sucked on it instead. The baby closed his eyes in satisfaction and made gurgling sounds. Seijuro fell silent as he deemed that his attempts are rather futile.

"I still don't like you that much, you know..."

The baby's eyes opened up, revealing irises as blue as his blinked at his older brother before showing a smile and staring. Seijuro stared back at his brother, not being able to keep himself from being mesmerized. Unknowingly, a smile graced on his lips. "Hello, Tetsuya. My name is Seijuro and I'm your big brother... and I take it back, I think I like you now"

Tetsuya just giggled in response.

Seijuro found himself smiling as he started cooing at his little brother, his lego collection lay forgotten on the floor. He decided, maybe having a brother wouldn't be that bad after all.

Shiori had to stop himself from squealing madly and making unnecessary noises upon seeing her older son tending with care towards his younger brother. She then went back to the master's quarters, opened one of the drawers and took out a camera.

Discreetly opening the door back to the nursery room, she began snapping pictures.

Both Masaomi and his wife weren't really that surprised when Tetsuya's first word had been 'Sei-nii'.

Six, closing to seven years have passed since then and Seijuro remained the dotting big brother he is.

"Are all your things inside your backpack?" A fourteen, almost fifteen year old Seijuro asked as he walked his brother towards his class. The first grader nodded at his older brother before responding.

"Yes, Sei-nii."

"Water?"

"Already here"

"Towel?"

"I have it, Sei-nii"

"If something happens, you know who to call, right?"

"Hai! Call Sei-nii first!"

"That's right" Seijuro patted his younger brother and ruffled his hair. "...and if someone bullies Tetsuya, what will he do?"

"Tell Sei-nii of course and he'll chase them away with his scissors!"

"And that is because?"

"Sei-nii is Superhero big brother!"

"And Sei-nii will always?"

"Save Tetsuya!"

"That's right, now run along... no wait, walk carefully and look where you're going"

"Hai! Bye Sei-nii!"

Seijuro waited until his younger brother is out of sight before walking back towards their family car and telling the driver to drive him straight to Teiko Middle. His current musing - which mainly consisted of basketball - came into a halt when he noticed something. "What's our family photo doing here?"

"Young master Tetsuya planned to use that during show and tell. He must have forgotten it"

"I assume it's today"

"Yes, young master"

"I see..."

"And young master... Your brother, I think he really wanted you to be there personaly for the activity but he must have thought that you're too busy and won't have time for him"

Seijuro frowned at that. Yes, he's busy but he'll always have time for his brother. He'll always make time for him.

"Turn around" The teen told their family driver before dialing a number "...Shintaro, I won't be attending some of our morning classes. I want you to tell our professors about it. Tell them that it's an emergency. And tell Daiki to attend today's practice"

"I get it, would there be anything else?"

"No that's all"

"Okay then. Classes will start in half an hour. I still need to prepare" Seijuro simply hummed in response before ending the call.

"We have arrived, young master" The door was opened, letting the teen out.

"Stay here and wait for my call" The driver nodded and remained standing, ignoring the curious looks he was getting. Really, it was nothing in comparison with what his masters would get on a daily basis. If it's giving the aura of intimidation, the Akashi's can tell you lots about that.

"Tetsuya..." Seijuro called unto his younger brother, immediately spotting the teal haired boy. Due to his brother's unique physical trait of having a low presence, it had always been hard for people to know where the young boy is. All except Seijuro. For some reason, it had always been easy for him to spot his younger brother wherever he may be.

Tetsuya rushed towards his brother and hugging him up, sobbing. The tears immediately caught the older boy's attention. "Tetsuya, tell me what happened?"

"I got scolded by my teacher because I forgot to bring something for show and tell"

"Did your teacher shout at you?" A small nod. Seijuro frowned at that. He's the overprotective older brother all right! He never let harm befall on his cute little brother. Heck he won't even let a single fly land on Tetsuya and yet the nerve of that teacher to actually shout at him? Unforgivable.

"She told me that if I can't show something she'll give me a bad grade and she'll tell Tou-san and Kaa-san" Tetsuya clutched unto his older brother, sobbing. "I don't want them to be mad at me, Sei-nii"

"Don't worry, They're never going to be mad at you" That's it. By tomorrow, that teacher won't be stepping inside his brother's school.

"Really?"

"Yes, really" Seijuro wiped the small tears that have tainted his brother's cheeks. "Big brother is suppose to bring you your show and tell item but the driver told me that you actually want to ask me personally to be here. Is that true?"

"Yes"

"Then why didn't you say so?"

"Because you're busy and you have school. I don't want to disturb Sei-nii"

"And since when did you became a distraction?"

"I don't know..."

"That's because it's a never. Tetsuya will never be a burden to big brother. You do know that, right?"

"So you're not mad?"

"And why would I be?" Seijuro chuckled as he played with his brother's soft locks. "I'm here now, do you want your Superhero big brother to be your personal show and tell?"

"Yes, Sei-nii"

"Let's go ahead then"

"I'm going to tell my classmates how cool you are!"

"I am cool?"

"Yes and that you're the best big brother in the whole big universe!" Tetsuya excitedly did some hand motions.

"I am your only big brother"

"I know and you're the best brother ever, ever"

"Tetsuya is the best brother too"

The younger boy beamed at that. He can't wait to tell everyone how cool his big brother is.

First request done since it's the easiest for me. XD
