Hey there. So, just gonna make this real clear from the beggining: this story has a heavy plot. There are triggers and obscene language and sexual content as well. If any of these things aren't what you were expecting then I completely understand if you leave now. If not then I hope you enjoy the story. It took me a couple of months to write it but I just had to after watching Big Hero 6 and becoming not only entranced by Tadashi but also unsatisfied by the amount of screen time he got.

Prologue

The lab was practically empty with no one but Tadashi working on his latest upgrade for Baymax. The smell of cold coffee lingered around his chilly desk. He rubbed his eyes as he kept twisting a bolt into place. Medicine; who would have guessed? In the end the robotics student was dedicating his time and putting effort into a project that involved medicine of all things. He took a moment to shift back and take in his work. A subtle smile spread on his lips at the white round machine as he recalled what had brought him to that moment.

"Good afternoon, I'm Tadashi Hamada. Um, this is my project. Simply put he's a nurse robot. I was instructed to bring him over to the medical department to test him out. If you have any suggestions at all, feel free to comment." The boy presented his creation and let Baymax take it from there.

Soon everyone had interacted with the mechanism and was admiring both the perfection of the device as well as Tadashi's knowledge in its making. He had thanked everyone for their participation as the class ended and all the students dispersed when a particular girl made her way towards him.

She wasn't very tall and had seemed quite inhibited and classy in her white doctor's coat, a grey textured shirt, white pants and all white sneakers.

"Excuse me." She called to Tadashi who had his back to her as he picked up the box that Baymax was kept in. As soon as he saw her his expression changed. His pupils dilated and his heartbeat went a little faster. She gave a meek smile as he looked down to her.

"Yes?" The boy responded in a voice a bit hoarse.

"Sorry..." She tittered a bit awkwardly before going on. "Uh, I really liked your invention..."

"Thanks." He grinned with a bit of a nervous tick and she giggled at that which made his cheeks flush a bit as he rubbed the back of his neck.

"Um, I just wanted to give you a suggestion, uh, well, I noticed that when I questioned uh, Bay..." She trudged out the bot's name while making confused eyes at Tadashi trying to make sure it was correct.

"Baymax." The boy helped her finish the word and she nodded.

"Yeah, Baymax about heart attacks he had all the information but didn't have any immediate treatment."

"Oh. I see."

"Don't get me wrong, I really did love him. I just...you know...wanted to help in anyway." She looked down quickly then back up.

"No, it's fine. I asked for ideas so..." The boy nodded without finishing the phrase that the girl had understood nonetheless.

"Okay then...well, I'm gonna get going." She smiled in relief as she slightly stepped back.

"Yeah, sure thing." Tadashi motioned towards the exit with his hand and smiled back.

The girl turned and started to the door. As she took her first few steps Tadashi took in the full sight of her again. Her lengthy ginger brown hair moved lively with each footstep and it made Tadashi smile to see her driven demeanor. He quickly turned though and searched for a pencil as he flipped open his notepad and wrote down the words "heart attack" to remind himself of modifications to be made.

After Tadashi was finished setting up his desk for the next day he dragged his drowsy body out of his lab and made his way to his motorcycle. Reaching the Lucky Cat Café the boy silently entered the front door making sure not to wake up his aunt at such an hour. Carefully stepping up to his room he finally began to unwind but not for long.

"Again?" The older Hamada groaned as he stepped into his empty bedroom. He spun back towards the door and grabbed his helmet as he fluidly went down the steps.

He already knew where his brother would be: bot fight. It was tiresome for him to have to study all day and still have the responsibility of getting his little brother out of trouble but he would never give up on Hiro. If there was one thing that Tadashi was, it was dedicated. Speedily riding through the vividly colored streets of San Fransokyo Tadashi could feel the chilly wind hitting his face and thought of how Hiro could get a cold from being out at this time.

"Hiro!" He called out to his brother as he caught sight of him in the midst of a crowd full of unfriendly looking teenagers. Hearing Tadashi's unmistakable gruff voice the younger boy turned and gave his brother a sly smile while walking towards him.

"Hey, big bro. Come to see my awesome bot destroy these guys?" Hiro teased his already irritated brother.

"Not even close." Tadashi said shaking his head with an ironic smile. He reached out and lightly pulled on the younger Hamada's left ear just enough to make the kid complain as he led him to the bike.

"Ow, ow, ow...No need for violence." Hiro insisted on teasing his brother with a grin although his ear was red. Tadashi let out a slightly amused breathe as they mounted the bike.

Just then bright headlights shined on the two brothers and a car horn resounded telling them to get out of the way. Tadashi looked back with a lump in his throat as he tensed up. It was a dangerous part of town and they could be sucked into a fight at any moment. Squinting to get a view of the driver he noticed a familiar face.

"Wait a minute..." He whispered to himself, forgetting to move at all.

"What are you doing, move out of the way." The older boy heard Hiro's annoyed tone as he pulled him back by his blazer.

Something in the back of his mind was hoping it was just an illusion of the smoggy air and a tired brain but he was sure that he had seen the same mocha eyes as he had once seen at his collage.

As the vehicle cautiously maneuvered out of the narrow street the driver saw Tadashi's honey brown irises glimmer from the car's strong light and focused on the guy's face. Now he was sure... rather, they were sure. That was the girl who had gone up to Tadashi after his presentation in the medical building at SFIT. Her intense eyebrows knitted down and her pupil grew immediately as her grip on the steering wheel tightened to the point that you could hear the rubber tensing up against her palm.

The girl held her breath and bit the inside of her lip.

"Oh no."
