Hiro: 15

Tadashi: 18

So this is a request from Tweets Sweets. They wanted me to explain why Hiro's afraid of perfume. First off, just to clarify, he's not afraid of perfume per say, more than he just doesn't like it. Just wanted to throw that out there. (He's totally afraid of perfume, but the little shit refuses to admit it XD). Also, I recall a guest asked me for this same thing, but I didn't really have an idea for it until now, so sorrrryyyyy XD I think a few people asked for this actually so that's why I picked it.

Anyways, let's get it on with.

Normal POV

Tadashi and Hiro Hamada were both at SFIT, but were doing completely different things. The older boy was absorbed in homework as usual, while the younger was busying himself with whatever he could find in Tadashi's lab that looked interesting enough.

"How many oxygen atoms are in 5.89 grams of carbon dioxide gas?" Tadashi asked all of a sudden, sounding frustrated.

Hiro plucked a piece of gum from the packet he found in one of Tadashi's drawers and set it down.

"Don't care. Let's do something fun." The younger suggests, swiping the homework from Tadashi and throwing it carelessly on the ground. The elder, annoyed, picked up his homework and pretended to brush all of its dust on Hiro's messy hair.

"I mean it Hiro. This homework is annoying and I need to finish it and have it turned in to Professor Eric in twenty minutes." Tadashi said, glancing at his watch.

Hiro sighed and rolled his eyes. He supposed the sooner Tadashi finished his work they could do something that was actually interesting.

"What's the question again?" He asked.

"How many oxygen atoms are in 5.89 grams of carbon dioxide gas?" he repeated, groaning and slamming his head on his desk.

"Really bro? pft, that's like 10th grade chemistry." Hiro said cockily.

"Okay then smart one, how do you do it?" Tadashi challenged.

"C'mon Tadashi, you're smarter than this. Avogadro's number ring a bell?" Hiro asks, genuinely surprised that Tadashi didn't remember.

The elder face palmed himself. "Shoot! I knew that! I really did! It's just been so long since I've used it." Tadashi defended, angrily scribbling the equation down.

"Sure you did." Hiro snorted.

"I did!" Tadashi insisted. He vigorously scribbled numbers down and muttered to himself. "1 mole of CO2 and…2…moles O…and…"

"It's 1.61x10^23 atoms." Hiro said before Tadashi could finish. The younger smirked at the glare he received from Tadashi.

"I was getting there." Tadashi grumbled, boxing in his answer, which matched Hiro's straight to the decimal place.

"Wait no! It's just 1.6, not 1.61!" Tadashi cried out in victory. He crossed him arms and faced Hiro with a smirk of his own.

He was confused as to why Hiro's smirk didn't falter. "Bro, I just proved you wrong. Feel free to hang your head down in shame any time now." Tadashi said with raised eyebrows. To the elder's shock, Hiro's smirk simply grew wider in size.

"Check again." Hiro said with a wave to the paper.

"What is it?" Tadashi asked, scanning the problem over.

"Sig figs. There's three, not two." Hiro said with a huge smirk, hand on his chin in a bragging manner.

"How did you know that?" Tadashi asked sourly.

"Well you said 5.89 grams. That's three significant figures." Hiro said with a shrug. "Therefore three sig figs." He said as if it were obvious, which in his eyes, it was.

"I can't believe you remembered all that without even looking at the paper. And without a calculator. How do you even do that?" Tadashi asked in annoyance.

"What can I say big bro? I'm a genius." Hiro said with a laugh.

"At least I'm not cocky." Tadashi said.

"At least I don't ask my brother for help on HIGHSCHOOL level work." Hiro said, sticking his tongue out.

"At least I don't get in trouble for blowing stuff up in the café!" Tadashi shot back.

"At least I know how to have fun!" Hiro shot back, hiding laughter.

Most would assume they were arguing, but they knew it was just friendly bantering.

"At least I'm not afraid of-

"Don't say it!" Hiro warned with wide eyes.

"Of-

"No!"

"Scared of-

"Tadashi!" Hiro cried out, waving his arms around.

Just then, Gogo burst into the room followed by Wasabi, Honey Lemon and Fred.

"Alright, what the hell is going on? None of us can get any work done with your childish sibling bickering." Gogo spat.

"Hiro's afraid of-

"No!" Hiro cried, rushing over to Tadashi and covering his mouth.

"He's utterly delusional." Hiro said, evading Tadashi's attempts to break free.

"What are you afraid of Hiro?" Honey Lemon asked.

"Yeah, I'd actually like to hear this." Gogo said with a smirk.

"Nothing." Hiro responded quickly.

Tadashi then licked Hiro's hand, causing him to let go in disgust.

"PERFUME!" Tadashi cried out once Hiro let go.

"GROSS! Did you just LICK my hand?!" Hiro asked in mortification.

"You're scared of perfume?" Gogo asked with a raised eyebrow.

"Okay, I'm sorry, but that's really unsanitary Hiro. Do you have any idea how many germs could've been on Tadashi's tongue?" Wasabi chided, squirting sanitizer on his hand.

"Like he cares." Tadashi murmurs. "The kid doesn't even wash his hands before eating." This earned him an elbow to the ribs.

"Why are you scared of perfume?" Fred asked.

"I'm NOT scared of perfume!" Hiro insists.

"Oh that's good because Honey Lemon's got some in her purse." Gogo states, pointing at the hot pink bag.

Hiro noticeably scoots away from Honey Lemon, causing Fred, Wasabi, Tadashi, and Gogo to laugh. Honey Lemon throws him a slightly sympathetic look, but everyone knows she's hiding a giggle herself.

"Hiro, why on earth are you afraid of perfume?" Honey Lemon said.

"I'm NOT afraid of it! I just don't like it. There's a HUGE difference." Hiro said defensively.

"Hiro, you're scared of it." Tadashi argued flat faced.

"You have no proof." Hiro fired back.

"Honey Lemon, toss me your bag." The older brother said. The bubbly blonde did as he asked and he pulled out the bottle.

"See this?" Tadashi asked tauntingly, biting back laughter.

Hiro shrugged. "Doesn't bother me." He said nonchalantly. But when Tadashi advanced toward him, it was another story.

"Okay! I get it! I'm not comfortable around that demonic liquid toxic!" Hiro wailed, begging Tadashi to put it away. His eyes were wide and fully on guard, as if the perfume would come out and kill his family. He practically had tears forming in his eyes, but refused to let anyone but Tadashi notice them.

"Say it." Tadashi demanded.

"No way!" He protested. Not while his dignity was on the line. Tadashi smirked and opened the cap off of the bottle. He shot Hiro an evil, challenging look.

"I-I'll N-never say it!" Hiro wailed, though everyone could see that his walls were cracking.

Tadashi was coming toward Hiro at a distance he wasn't particularly comfortable with. Hiro made a scared beyond explanation face and backed up into the wall.

"Say it and I'll put the perfume away." Tadashi says evilly.

Hiro gulped, but shook his head stubbornly.

When the perfume was about three inches from his face, Hiro squealed and shielded his eyes. Wiping his tears in secret, he glared something fierce at Tadashi.

"Alright. I'm a little less than cool around perfume." Hiro grumbled unwillingly, waiting for Tadashi to move the poison away from him. When he finally did (way too slowly in Hiro's opinion), the younger visibly relaxed.

"But why?" Wasabi asked.

Hiro pulled at his hoodie uncomfortably. "Uh, that's not important." He said vaguely.

"May not be, but it probably makes a damn good story. Now hurry up and tell us before we make Tadashi tell us. Trust me, if he tells us the story, it'll just be worse for you because he won't leave out any juicy details." Gogo advised.

"Hmph. Alright. I'll tell you the story, but you're all just going to laugh." Hiro said with a frown.

"I promise I won't." Honey Lemon assured.

"Me too." Wasabi said.

"Same." Fred added.

"No promises." Gogo and Tadashi said in sync.

"Jerks." Hiro muttered, glare not leaving his face.

"Alright, so it happened when I was like 6 or 7. Aunt Cass and Tadashi were starting to get really busy with their work, and so Aunt Cass hired a babysitter to watch me now and then. I didn't like the idea of having some weird old lady watching me, and Cindy was no exception. She smelled like rotten onions and would always call me 'sugar plum'." Hiro said, wrinkling his nose.

"Wait, what was Tadashi 'busy' with?" Honey Lemon asked.

"I was staying after every day to look at colleges and stuff. I know it was early, but you can never be too ahead." Tadashi says with a wave.

"Go on with the story." Gogo said impatiently.

"Right. So whenever Cindy would come, she would always treat me like I was a dog or something. Spraying water on me when I did something she didn't like, giving me a 'treat' every time I did something she did like, even want to teach me 'tricks' or whatever." Hiro said with a roll of his eyes. Tadashi and Gogo snickered at this.

"What do you mean by tricks?" Wasabi asked.

"Like hopping from one couch to another, rolling over, other stupid stuff." Hiro said in annoyance. The others gestured for Hiro to continue with the story.

"So one day, I snuck some gummy bears in my room and that was against the rules, so Cindy sprayed me with the most obnoxious smelling perfume I ever had the displeasure of coming into contact with, and it went straight into my eye." Hiro said in anger.

"Why would she do that?!" Honey Lemon exclaimed.

"She didn't realize it was perfume. She thought it was water." Tadashi said, sounding angry himself. Apparently he didn't like this part of the story either.

"And then what? Fired obviously, but did your aunt go off on her like Wolverine?" Fred asked.

"Aunt Cass was having a fit, but Tadashi really got pissed. He was all up in Cindy's face, yelling about how she didn't know the first thing about childcare and then went on to tell her that she better not reproduce with anyone because lord knows what would happen to those children." Hiro said, laughing again. Tadashi cracked a sheepish laugh at this as well.

"You really said that?!" Wasabi asked. Tadashi nodded, looking a little ashamed, but quickly changing to defensive.

"She was asking for it. What kind of daft hollow-brained idiot sprays a kid with perfume in the eyes?! We had to take Hiro to the hospital. We never saw her again though. The only reason I bring out perfume is to get Hiro to do something I want." Tadashi revealed.

The gang nodded in understanding while Hiro looked irritated.

"You're a jerk." He said, nudging Tadashi.

"Aww, don't be like that sugarplum." Tadashi teased, causing Hiro to push him away in embarrassment. Tadashi just laughed.

"I would never spray you with perfume, you know that, right?" He asked. Hiro looked up at him a bit apprehensively.

"Promise?" He asked shyly. Honey Lemon and Wasabi 'awwwed' at Hiro's tiny voice, causing him to blush.

"I promise bonehead." He said, pulling Hiro to him for a hug.

"Oh right. Hey guys, you know Tadashi's afraid of-

"OH! Look at the time. Aunt Cass wanted us home. Sorry guys, we'll catch ya later." Tadashi said, pulling Hiro out before he could finish his sentence.
