**Hey, guys! Just here to say again that this is not actually my original idea!

By the way, a really nice person told me in a review that technically "Niisan" exclusively means "big brother," and not "little brother." If there's anyone out there who can tell me technically what Hiro would call Tadashi, something instead of "Niisan," that would be great!

Also, special thanks to the YouTuber Markiplier who inspires me to do great things like write fan fiction for all of you wonderful people! He's my living, breathing inspiration, and he always tells his fans to believe in themselves, and that means a lot to me, and I'd like to spread the same kind of positivity that he does through my own pieces of work that people take time out of their day to read and enjoy. If you ever need a little extra laughs in your life, look up Markiplier on YouTube.

Thanks for reading, I had no idea that people would like my story this much! Thank all of you lovely people who have decided that what I wrote was worth their time. That means so much to me!

I'll stop blabbering, now. Thanks for reading!

Hiro walked through the stone steps of the San Fransokyo Institute of Technology. following behind Tadashi, though just barely. His mind still reeled at the thought of what happened the day before. He stopped at the threshold of double glass doors, swaying slightly as the palm of his hand caught the handle. Tadashi had already entered inside, but he turned, just inside the foyer, and smiled.

"What?" Hiro asked, though he already knew why.

"Why do you think?" Tadashi winked. "Still a little bit mind blown?" He imitated his head exploding, splaying out his fingers and mimicking an imaginary bomb, his lips rounding dramatically. He dropped his hands and grinned, bouncing slightly on the balls of his feet. Hiro looked up at his big brother and smiled back.

"I just… can't believe it."

"You're acting like this is a bad thing, little brother." Tadashi stood by Hiro in three steps in three short seconds with his long legs, and before Hiro could protest, Tadashi picked up his little brother and slung Hiro over his shoulder. Hiro's world spun for several seconds, but Tadashi didn't wait. "Come on, we have to tell the others. They don't even know!" He began jogging toward the elevators, while Hiro grabbed onto Tadashi's jacket, trying to gain any kind of composure. He noted other students in the school staring at the both of them, but he couldn't be bothered by them, anyway. His head spun, and his stomach hurt, as Tadashi's shoulder dug into it painfully.

"Woah dude, really?" Fred asked for literally the fifth time in a row. Go Go pushed him out of the way, clearly irritated. She chewed audibly on a piece of gum, and stared at Hiro. He forced himself not to flinch, slightly. The expression on her face looked almost angry—intense.

"So, you met the big man?"

Hiro scratched the back of his head, reluctantly. "Yeah, I guess I did."

"What was it like?" Wasabi asked excitedly, almost pushing Go Go out of the way, though he flinched from the look she gave him. He turned to Hiro excitedly, and a certain gleam in his eye showed a scary kind of obsessiveness.

"You are making Hiro-san anxious," Baymax stated, matter-of-factly. Wasabi turned to him, the look on his face incredulous.

"Man, you don't understand. Hiro met Iron Man!"

"You are correct. I do not understand. Who is this 'Iron Man'?"

Wasabi groaned theatrically and facepalmed himself. "See? Baymax is really intelligent—"

"—Thank you—" Baymax interrupted, his tone happy.

"—But Shi-kun," he said, turning to Tadashi, "you really need to program more important stuff into Baymax, like who Iron Man is."

Tadashi laughed. "Sorry, Wasabi-kun, but I programmed Baymax to be a healthcare companion, not as anything else."

"I'd think that kind of information would be pretty important," Fred said, rolling past Tadashi on a skateboard, holding up his hands in an innocent, conciliatory gesture, a smirk on his face.

"Guys, that's not really the point though," Honey Lemon protested, frowning. She pushed her rounded glasses up her nose. "The point is, Hiro-kun and Tadashi-san met the Iron Man. And he wants to work with them."

"Wait, how did you—" Fred turned to Honey Lemon, who started blushing as she glanced at Tadashi, who shrugged and held up his phone, waving it teasingly.

"Hey, I had to tell someone. You didn't say anything, Honey-chan?"

"What do you mean he asked you to work with him?" Fred asked, incredulous. "Like, as his young protege sidekicks or something? That's sick!"

Hiro shrugged, frowning. "That's what it sounded like, anyway. I think he's more interested in Tadashi, though. I mean, he made Baymax, right?" He wasn't sure whether or not stating that Iron Man was so rude would benefit him anything. The entire room seemed too enamored with the thought of him and Tadashi meeting Iron Man. Personally, Hiro wanted to never see the man again, but Tadashi seemed to, which bothered him.

"But he's seen what you can do with your bot. Remember, he wanted you, too," Honey Lemon reminded Hiro, wrapping one arm around him. "Remember, you're pretty smart, too. You graduated from high school at middle school age. That's not unimpressive, Hiro-kun."

Hiro couldn't help but blush at this. Honey Lemon giggled and hugged him, squeezing his shoulders slightly. "I'm sure that you'll do fine. This will be perfect for a resume, when you're old enough."

"Hey hey, Hiro's a little too young for that still though, don't you think?" Tadashi teased, smiling.

"Says the over-protective big brother," Go Go commented, sarcastically. "Be glad Hiro-kun doesn't have a girlfriend or something. Though, that would be cute, too." She grinned, and Hiro rolled his eyes.

"I'm just looking for what's in his best interest is all," Tadashi argued, some heat in his voice.

"Hey now, Go Go's just teasing. You know that, don't you, Shi-kun?" Fred replied, patting Tadashi on the shoulder. "Besides, you still haven't explained what happened, exactly. You kind of left out the part where Iron Man asked you guys to work with him."

The night before...

Red and blue light from the neon signs on the side of the street shone on the wet concrete. Rain pattered onto Hiro and Tadashi's raven black hair. Hiro clutched the broken bot in his hand, blinking against the rain. Tadashi stepped just inside the doorway of the bot club, and Hiro ducked his head.

Tadashi let Hiro down onto the concrete outside of the bot fight club. Hiro half wished that Tadashi wouldn't—his legs shook as he stared up at Tony Stark, the man known as Iron Man. Someone Tadashi looked up to for years. Tadashi was exceptionally tall to Hiro, and Tony Stark stood similarly, and slightly taller. His body was more built, and his stance suggested a slight haughtiness or joking demeanor. Hiro wasn't sure which as he squinted at the celebrity in the rain. The quote to "never meet your hero" rang in his mind.

Tadashi stepped slightly to the front of Hiro, whether subconsciously or not, the younger brother wasn't sure. Tony Stark raised one eyebrow, and his head inclined ever so slightly, as if in approval of Tadashi's protectiveness of Hiro.

Despite himself, Hiro stepped out from behind Tadashi's barrier, raising an eyebrow. He started to form his own mental barrier. Whatever Tony Stark's intent was, Hiro felt a kind of hostility towards him, not knowing where the feeling came from. Maybe it was the way Tony Stark stared at the both of them. Maybe it was the bad lighting, the flickering neon lights lighting up the man's black shirt and Tadashi's familiar cap.

What do you mean you 'found us'?"

Tony Stark chuckled, and a certain foxish gleam in his eye shone. Hiro wasn't sure whether that disturbed him or not.

"I didn't mean to alarm you, Hiro," he replied. "I was merely interested in the both of you. Tadashi, correct?" he asked, referring to Tadashi, who nodded mutely. "You created Baymax, and I must admit that I am impressed with your skills on making large, robotic marshmallows. And Hiro, your robot?" he asked, nodding to the robot in Hiro's hand.

"Yeah, that doesn't make you any less creepy," Hiro said, sarcastically. Tadashi may like Iron Man, but what Hiro knew of him, he seemed… too haughty. Hiro wasn't even sure why he was being this rude, but at the same time, Tony Stark shouldn't have even known who the Hamada brothers were, let alone finding out where they were that night.

"Hiro-kun," Tadashi snapped. "Don't be rude."

"It's perfectly alright Tadashi, if Hiro is a little distrusting. In fact, I'd be concerned if he wasn't a little on the defensive side. I was mainly interested because of Baymax, but I had not realized that Hiro had a similar talent, as well. You graduated early from high school didn't you, Hiro? The both of you would make quite a team. Since you are brothers, it would make sense."

"Who is this Jarvis?" Hiro asked, raising an eyebrow. "What do you mean by an artificial butler?"

"He's an AI computer installed into all of my suits," he replied. "Much like Baymax, except he's less physical, and not a walking talking marshmallow."

"And you made him?" Tadashi asked, his mouth slightly gaping. Now that Hiro looked up at his big brother, he could tell that Tadashi looked slightly pale, and his hands clasped and unclasped, as though clammy.

"I make a lot of things," Tony Stark replied. "So do you, which is why I am interested in the both of you."

"In a pedophelic way?" Hiro murmured, and Tadashi shot him a pleading look.

"I like you, kid. In a non pedophilic way," Iron Man replied, his eyes portraying what Hiro could only describe as sassiness. "Anyway, I wanted to drop by, and see if you were interested in coming to see me in my wonderful abode, and maybe talk about inventing a few things if you're less inclined to not spend time with someone important, like me. You know, robotic kinds of things. It would be both in our best interests. You intrigue me, the both of you. And trust me, very few things intrigue me." He extended a small business card to Tadashi, who took it warily. Without saying goodbye, Tony Stark turned and walked away in the darkness.

...

Hiro explained all of this in a few words, Tadashi adding in several details, some unnecessary. Hiro still felt unsettled about this as he looked at his big brother. Tadashi, though they fought sometimes, was Hiro's best friend in every way. Now that someone else had his full attention made Hiro feel a negativity towards Tony Stark. Much like when Tadashi had girlfriends, sometimes. Hiro bit his lip, feeling slightly disgusted with how selfish he was acting, but that was the best way he could possibly describe what he was feeling.

Not that he would ever admit it, but… Hiro felt fiercely jealous. In every way, Tadashi felt like the center of Hiro's world, and now that someone else decided to throw off his sense of metaphorical gravitational pull, that unsettled him. A lot.

Maybe I'm just overreacting, Hiro thought. But now that some hot shot gazillionaire decided to vie for Tadashi's whole attention seemed incredibly unfair.

"Hiro-kun?" Honey Lemon's voice brought him back.

"What?" he asked, blinking.

"You kind of zoned out for a bit there, buddy," Wasabi replied, waving a hand in front of Hiro's eyes. "You okay? Are you tired?"

Hiro pushed Wasabi's hand away. "Yeah, I'm okay. Don't you have something to work on?" His tone sounded slightly more irritated than usual.

Not that he would get away with that. Go Go raised an eyebrow, and Wasabi stared at Tadashi, and knitted his brows for a slight second towards him. The gesture was executed so quickly that Hiro wasn't sure whether or not it actually happened.

Honey Lemon placed a hand on Hiro's shoulder. "Hey Hiro-kun, do you want to go see something cool?" she asked. "I've been working on it for a few weeks, now. I think you'd like it."

"But—"

"Come on, everyone else has seen it. I've been dying to show you. You'd totally appreciate it, trust me." She gave him a push in the small of his back to show that fighting her wasn't an option. He wasn't exactly in the mood for a pep talk, but a small part of his mind tried to give Honey Lemon the benefit of the doubt. Maybe she was just trying to alleviate the awkwardness of the situation.

She led him past a small glass partition door that opened as they approached, and closing as they entered. Hiro looked behind him back towards the group. They were talking about something else, probably more about Iron Man. Tadashi looked excited and enamored about the subject. Something in Hiro's gut twisted mercilessly, and he turned back only to find Honey Lemon's face level with his, and extremely close.

"Ah-ah!" he cried out, flailing backward, his arms windmilling. Honey Lemon's hand caught his arm, and he stopped, though he stared at Honey Lemon.

"Quiet, Hiro-kun!" Honey Lemon said, her eyes suddenly more intense.

"That was kind of unnecessary," Hiro said, frowning.

"So is your attitude towards Iron Man," Honey Lemon replied, scowling slightly. She turned around and began shifting around several instruments on her desk, almost for lack of anything else to say. Though Hiro knew better.

"Am I supposed to question why you're saying this?" he asked, sarcastically.

She seemed to find what she was looking for, because she turned around again, holding up a pair of glasses. "Put these on."

"You're avoiding the question."

"Put them on."

Hiro sighed, and took them from her, and sliding them on, he gasped, staring at Honey Lemon. He rubbed his eyes and looked through them again.

"Well?" Honey Lemon asked. "What do you think?"

"These are great, but… Wait, you're just trying to distract me, huh?"

"Not really. I did want to show you the glasses. Thermal imaging in a pair of normal glasses. Cool, huh? But that's not really the point." She took the glasses away from him, gently. "Hiro-kun, I know you're upset."

Hiro laughed, nervously. "Me? Nervous? What? Are you sure you're not talking to someone other than Hamada Hiro? Because I think you're not. Wait, what?" He frowned.

Honey Lemon giggled. "You know, for a genius, you can be a real doofus, sometimes. And you're a horrible liar."

Hiro sighed, and Honey Lemon sat down on a stool in the corner, her long legs swinging outward. "You're upset with Tadashi-san, aren't you?"

Hiro scratched the back of his neck, letting out a slow breath. "Well, not really."

Her long legs swung again, but this time upward, and crossing into each other in her lap. She leaned forward, gripping the rim of the stool over her legs, which Hiro noted, were covered with leggings, and several pictures of cats in large purple and blue universes were imprinted on them. "Well?" Honey Lemon asked.

"You want an explanation? I thought you knew everything, already."

"Something's seriously wrong with you, Hiro. You're just jealous of Tony-san, right?"

"Who wouldn't be jealous? He's a millionaire."

"That doesn't matter, Hiro-kun. I'm talking about Tadashi's lack of interest in you."

Hiro winced. "It somehow sounds worse put into words."

"So you are jealous," Honey Lemon replied, narrowing her eyes.

Hiro let his shoulders slump. "I'm sorry, Honey-chan."

"For what?"

Hiro hesitated, frowning. "I've been really rude, is all. I guess you are right, I am jealous of him."

"It's a perfectly normal reaction. It happens all of the time between siblings. You want Shi-kun's attention, but he's not giving it to you. He's focusing most of his attention on Tony-san."

Hiro pursed his lips. "I guess."

"Hey, don't worry about it." Honey Lemon suddenly stood beside Hiro, and she knelt down to his level. "Remember, you're Hamada Tadashi-kun's little brother. He talks about you all the time, you know. Some baka celebrity won't steal all of him from you. Remember that, Hiro-kun." She ruffled his hair, turning the front part of it into a bird nest floof.

"Really?"

"Yeah. Now let's get back before Shi-kun realizes I'm giving you a pep talk. Just know that Tadashi-kun still loves and cares about you, okay?"

"Yeah," he replied. "Yeah."
