{A/N: Yes, I am taking requests! Also, this collection may not go in order. Such as now, takes place the earliest of the 4 I've written. Also, even though I typically have Tadashi 6 years older than Hiro, I'm having this one take place between Tadashi and Hiro's birthdays, so he's ten and Hiro is four.

Enjoy!

It had been 8 months since the accident had killed the biological parents of Tadashi and Hiro Hamada. They'd been driving to a date night when the sleep-deprived truck driver hit. Ever since, Tadashi had taken his little bro under his wing, through the good and bad phases of attitude. The kids' forms were signed to transfer them to San Fransokyo house of juvenile men, an all-boy orphanage, when their father's sister signed the adoption papers and took the boys in as her own. And based on how these past eight months had gone, it was so much more than she'd imagined.

One was a toddler, and one was ten. That made for two very needy bodies suddenly living in the woman's Painted Lady, in which she ran a successful cafe out of the ground floor. They were both going through something that was way too emotionally heavy for kids their age to have to go through. In fact, it was too much for anyone to have to go through. But these two boys were unstable, and quite the handful. Cass had fallen for them though. They'd taken her heart and run off with it, providing her with the family she needed.

The toddler was fine behaviorally. Not much more than she'd expect from him, he was handling the news very well. Cass secretly wondered if he understood what had happened.

The ten year old was a pretty good kid too, although he could get into his moods. There were times when he would shut down, snapping at everyone he talked to and refusing to do chores and homework.

One time Hiro ran down the stairs, tripped, and fell. The boys' Aunt was busy tending the lunch rush, so she called Tadashi asking if he would clean up his younger brother. The response she received back from the ten year old was "Tell Hiro to stop falling down the steps, instead! I'm not his nurse!" That left Cass with a busy cafe, crying toddler, and disobedient fifth grader, all of which she had to care for at once. Boy, was that a fun day.

Things changed, though, and it all was because of a donut.

"Hiro, Tadashi! Can you come here?" As soon as the Aunt called, the two boys were downstairs, out of their shared room. They knew very well her reason of calling; the woman was running out for errands. That meant the two would have the house to themselves. "Café is closed, I'll be back in an hour, okay? Just some grocery shopping. I have my cell phone, call me if you need anything, okay?"

The two boys chimed in sync, "We love you, Aunt Cass."

"I love you too." She smiled, kissing both on the forehead before she headed out the door, the café's bell jingling to signal her departure.

Tadashi smiled at Hiro. "First one to the couch gets to pick the game." Having the longer legs and better coordination, it was no real contest. The two loved truth or dare, scrabble, clue, and nearly any other board game put in front of them.

An intense game of hide and seek ensued, Hiro at one point hiding in a cupboard. Tadashi never would've found him had he not closed the door on his t-shirt in a way where it stuck out a little. The game was followed by tag, which winded both of the boys.

"Running… Makes me… phew…" Little Hiro huffed, grabbing onto Tadashi's calf for support.

"Hungry?" Tadashi's face was red, the boy ruffling a hand through Hiro's hair. "Come on, we live in a café. Let's just grab something to eat." Tadashi picked up his younger brother and brought him downstairs to the ground floor, while he protested.

"Dashi, that's no good! Auntie Cass has told us before, no eating the bakery stuff! Plus, she'll be home soon! She can make us food! You know Auntie is the best cook ever! Maybe she's gonna make us wings…" The kid went on and on. Tadashi wondered when he'd take a breath.

"Hiro, don't worry." The older boy put Hiro down, making his way behind the counter. "Aunt Cass is at the supermarket. It's probably packed, plus she'll stop at Mrs. Masuda to chat, and then probably buy something at the bookstore." Tadashi reasoned, opening the display case and dropping a piece of fudge on a napkin.

"But Dashi… She said she'd be home in an hour…" Hiro pestered as Tadashi took a bite out of his treat to emphasize.

"Am I in trouble right now?" The older said, with a mouthful.

Hiro gave in after Tadashi finished safe and soundly, his brother moving aside as the small kid clambered up and grabbed a chocolate-frosted donut. He was reluctant, before sinking his little teeth into the sweet desert.

"HIRO!"

Aunt Cass scolded loudly, her voice triumphed over the entrance's bells. "My number one rule! No eating my stock!"

The supermarket was empty.

"I told you I'd be coming home, mister! Why did you break my rule?"

Mrs. Masuda was on vacation.

"And now you're trying to throw Tadashi under the bus? Save it, Hiro. I trusted you. This is disappointing."

The bookstore was closed.

Tadashi didn't intervene for him or anything. And when the older boy visited Hiro's grounding cell, considering it was their bedroom, Hiro wouldn't look at him.

"Boy, is Aunt Cass stressed. Those donuts were goners anyway." Tadashi tried to lighten his brother's mood.

Hiro shot the best toddler-glare he could muster. "This is your fault, you know."

Tadashi shook his head. "I didn't get caught."

"That doesn't change anything! That just makes it unfair!" Hiro sassed, hitting a palm to the bed in fury.

"Maybe if you didn't hesitate-"

"Maybe if you cared a little, I wouldn't be the only one punished here!"

Tadashi scowled, throwing his books onto his bed. "That's just rude."

"You're rude! Get outta here!" Hiro stomped over and stared out the balcony door. The Hamadas had a small deck of plants, which was hidden from the street's view.

Tadashi crossed his arms, huffing and walking back downstairs, where he passed by his questioning Aunt offering no answers besides "I'll be downstairs."

Tadashi cooled off from the fight by reading the newspaper and doing crossword puzzles. "Awh," he sighed to himself as the word 'reprimand' came up. "I goaded the kid… He looks up to me. He listened to me. And he got in trouble and I ditched him." The ten year old regretted his actions, and dropped his pencil. With a long, exasperated sigh, he shoved the puzzles away and stood up. He had to be the better man now. For Hiro.

The kid walked up to the third floor again, clasping his hands together as he stood in the doorway. "Hiro?"

No response.

"Hiro, please don't play games. I want to apologize."

Nothing.

Tadashi walked over to the lump on his little brother's bed. "Please, Hir-" Tadashi froze when the covers were pulled back.

The bed was empty.

Something whistled in Tadashi's ear, and he yelped.

"Tadashi? Hiro? You two okay up there?" The steps could be heard, she was probably on the second of third one.

Tadashi nervously laughed. "Yeah, Aunt Cass! We're good! We're uh… Actually having some serious bro code going on, so… We need to be alone for a bit, okay? Eheh… We'll be down when we're done!" He doubted that was believable, but it was all he had. Aunt Cass couldn't know that Hiro was missing.

"Uhm… Okay?" Aunt Cass was sketchy on it, but decided to let boys be boys.

Something moving caught Tadashi's eyes. It was the curtain near the staircase, blowing ever so slightly. Taking a screwdriver, Tadashi pulled back the curtain and prepared to fight whatever was making it move, holding out the tool threateningly. It was just the door to the balcony, which was left a crack open and causing the draft. Tadashi muttered some choice words as his eyes followed a trail of dirt to the edge of the balcony, before it disappeared. The brown footsteps were toddler-sized.

The ten year old threw the door open, running outside. They had a vine wall, which was built in a lattice that Hiro must've used as a ladder. Tadashi dropped his weapon and climbed down into a dark alley behind their house, slipping on one of the last steps and falling to the concrete. "Ugh," he muttered, dusting himself off. "HIRO!" Tadashi yelled, gaining his footing again. Where would a 4 year old be happy going? The kid shook his head running throughout the twisted alleyways. "HIRO!HIROOO!" Tadashi stumbled around a corner, tripping over a family's garbage and face planting to the ground. His brother was gone. A 4 year old boy, the only immediate family he had left, out on the streets of San Fransokyo alone. Tadashi didn't bother getting up off the ground. He was a horrible brother, a horrible person. He hated everything. And he started crying uncontrollably.

Tadashi Hamada had only really cried when he attended his parents funeral.

And just when he was at his lowest, Tadashi heard a small voice.

"Dashi? Dashi… a-are you crying?"

Tadashi drew in a hard sniffle, blinking and sitting up a bit. He was now eye-to-eye with small brown eyes, a button nose, and uncontrollable hair. "Dashi?! What happened?!" Hiro threw his arms around his big brother, sniffling himself. He didn't like it when Tadashi was upset.

"Hiro!" Tadashi quickly grabbed the boy, sitting up and pulling him into his lap. "Shh, Hiro… Tadashi is here…" The older brother nearly squeezed the life out of the tiny kid, happily crying over his shoulder. "I'm so sorry… For everything, Hiro. Promise me Hamada brothers stick together from this day on, no matter what?"

Hiro clung to his big brother. "I…" The two both wiped their eyes, nodding at the other. "Absolutely."

Tadashi cracked a smile, his eyes still glinting and glassy. "Let's get home before Aunt Cass finds out."

The older Hamada put the small Hiro atop his shoulders, carrying him back through the winding, shady back roads of their native city. Tadashi was extremely careful climbing the vine wall with one arm, cradling Hiro in the other. Once back safe and sound, the two grabbed each other's hand, sharing the last of the sniffles and agreed that the Hamada brothers would never fight again. The four year old yawned, and Tadashi picked him up.

After a few minutes of silence, he spoke. "Hiro?"

Out cold.

"From now on… I promise to be a responsible role model for you. You and I, we'll be the best kids around. We're gonna be an unbeatable team. I promise."

The kid had no heart to drop his little brother off into his respective bed. So the two crashed in Tadashi's curled up together in their dirty, pavement-caked clothes.

Aunt Cass knocked on the door at the top of the stairs. 'Bro Code'. They hadn't come down, like promised. "Hiro? Tadashi?"

When there was no answer, she pushed the door open. "Kids?" The lights were off. Where were they?

Her eyes panned left, past a folded up screen as she saw a larger lump than usual on Tadashi's bed. Creeping over, she found the two brothers all snuggled together. "My boys…" Aunt Cass snapped a photo on her phone, smiling at it. "They're the cutest in the world."
