"Hello! I am Baymax. Your personal healthcare companion."

Tadashi sighed. So far, things were going good with his project with Baymax's development going on schedule. He had managed to build in the essentials into Baymax's design but there was still a whole load of kinks to figure out. It worried him that maybe he wouldn't finish in time.

"Knock knock." Lily chimed as she entered the lab.

Tadashi smiled, holding up his arm for Lily to fit by his side, "Hey, g'morning!"

The two had gone closer over the few more weeks they worked together on their respective projects. Add in the usual texts, chats and e-mails despite seeing each other in person almost every day, it was pretty hard not to conclude the best had happened between the two nerds.

"He looks good. Hi, Baymax!" Lily grinned, squeezing Tadashi's side as he rested his arm over her shoulder. It felt right with her there.

Tadashi found out that Lily had a soft spot for his project, Baymax. It would be an understatement to say that he had developed an admittedly childish and uncalled for jealousy because of it, but seeing Lily light up whenever Baymax could, in some form or another, respond to her questions and statements made Tadashi work even harder into programming Baymax's intelligence design as best as he could.

"Greetings, Lily. What seems to be the problem?" Baymax still couldn't move around as much as Tadashi wanted him to. Neither could he scan anyone or use his built in apparatuses with any significant precision so, at the moment, Baymax was still an inflated bulk of a robot with part of his program installed. "Nothing, really." Lily smiled wider, making Tadashi's heart swell. "Better leave you to your work then, hm?" she said, squirming out of his hold, giving Baymax a wave with the robot returning one of his own.

Tadashi chuckled before once again hunching over the nearby workdesk to plan the next rig. Across the room, he could hear a faint humming from Lily as she had made herself comfortable by her ledge and started clacking away at her laptop trying to finish her dissertation.

He was never normally a gloomy person, Tadashi reflected, but he's never looked forward to a day as much as he had these past few months. Lily moving into the lab probably had a huge part in that. 'Lily moving in, huh', Tadashi sighed wistfully, 'I like the sound of that.'

"Watcha smilin' about?"

"Haa!" Tadashi screamed backing away from a mischievously grinning Honey Lemon, "N-nothing! When did you get in here?"

"Just now," she bubbled ", riiiight before you got that look on your face."

Tadashi looked at her suspiciously. "What loo-"

"Lily! You're here!" Honey Lemon chimed, walking over to cuddle Lily, cutting Tadashi off mid-sentence.

The gang adored the willowy girl he brought to the group. Gogo and Honey Lemon immediately took it upon themselves to flank her whenever she decided to walk out of the safety of his lab, considering how clumsy she could be. Lily always enjoyed hanging around with them, especially during the evenings when they all had to stay out late, with Fred being the comedian that he is, scaring Wasabi on purpose just to get that squeal out of him.

As the deadlines got closer and tensions getting higher, time for fun and games in the lab became rarer and rarer. Progress on Baymax's design wasn't going as well as Tadashi would've wanted putting him in a sour mood more often than normal. He was tired, hadn't slept for at least three days if you add all the hours together and extremely frustrated with how stubborn Baymax was being for the past two weeks.

Lily had noticed Tadashi's stress levels getting higher and higher every day. He had snapped at her at least twice that week but she understood how pressured he is with his project right now, with an initial demo happening for everyone in three days before the final one at the showcase. Because of that, she hadn't been working at the lab as often as she had before.

She would drop in in intervals sometimes, bringing everyone a freshly brewed thermos of coffee and a few snacks her dad made, always receiving an eternal echo of gratitude from everyone in the lab. She would sometimes come in in the morning and find Tadashi slumped, snoring and in the same spot she left him the night before, head often on her purple pillow. She would always make it a point to give him just a little extra of whatever she'd bring, hoping it would help somehow.

"Tadashi?" Lily called into the lab that evening. It was pitch black inside ever since a few minutes ago. Wasabi gave her a worried call that evening, telling her Tadashi wouldn't budge from where he sat at the lab. He was alone that night, everyone deciding to take a break from their work for that one evening, Tadashi being the stubborn exception.

"Who's there?" she heard him call out, a beam of light coming from his direction.

"Just me.", she said, stepping in, finding a short-circuited Baymax and an exhausted Tadashi. She gave him a wary smile, "Brought some snacks... and a blanket, among other things."

Tadashi, continued tinkering with Baymax with the flashlight in his mouth. "Uh-huh, Shanks.", he grunted.

Lily looked at Tadashi, then at Baymax. It worried her that he was pushing himself so much, sure this was important above everything else but was it really worth it to risk your health while creating a nurse robot? Very ironic if you ask her.

"Tadashi, I think you should take a break.", she said worriedly, not getting a response from the young man. "You've been at this for days, this isn't good for you. And trust me, future doctor here." Lily laughed dryly, still receiving a negative from her companion.

"Tadashi.", she said more sternly.

"I'm working, Lily.", Tadashi replied, placing the flashlight on the tabletop.

"Please. Just for tonight."

"Lily!"

Tadashi stood, knocking over his toolbox and startling Lily. "I'm trying to work. Please understand!" Tadashi said angrily.

"And please understand that I'm worried about your health!" Lily replied just as heatedly, snapping out of her surprise and crossing her arms.

"The deadline is in three days! THREE DAYS! How do you expect me to finish in time if you keep distracting me?!"

"How do you expect to finish at all if you develop and ulcer before presentation!"

"I can't concentrate while you're here!"

"I can't sleep knowing you're killing yourself!"

"I'm fine!"

"You're not fine! If you were, we wouldn't be having this argument!"

"Lily!"

"Tadashi!"

Standing nose-to-collar, Tadashi and Lily stood stubbornly in front of each other, resulting to a battle of will considering the verbal one bore no fruit. "Seven minutes." Lily grumbled. "Lie down for seven minutes and I'll let you off the hook." Despite all the yells he threw at her, Tadashi still knew Lily just wanted the best for him. He was just so stubborn and tired to think rationally. He sighed, "All right. Seven minutes. After that, I go back to work." Lily smiled triumphantly, "Deal." Receiving a quick kiss on the cheek from Lily, Tadashi couldn't help but smile.

Lily laid out the blanket she brought and sat on top of it, purple pillow in hand. "I'm sorry for yelling at you. I was just... tired." Tadashi sighed, resting his head on the pillow Lily set on her lap. "Uh-huh, thought so." Lily chuckled, running her fingers against Tadashi's scalp, scratching a few spots here an there, getting an appreciative hum from him. "Seriously, I am really sorry.", he mumbled, rubbing his thumb against Lily's free hand. "I know.", she smiled, seeing him slowly drift off. "I'll make it up to you,", he yawned ", I promise..."

"I'm counting on it." Lily smiled, finally seeing Tadashi doze off.

Another month and a half passed for the students with Lily already back at the lab more often than before. Tadashi had been working tirelessly with care on Baymax, already past his 80th or so test. He was excited that morning, elated in fact. 'This is it.', he thought, getting ready to run Baymax again.

Lily had been painfully patient with him. The morning after their fight, Tadashi woke up with a fresh mind, well-rested eyes and a very numb, slightly drooling Lily who sat still for the rest of the night to act as his very own human pillow. To say he was touched was an understatement. Ever since he had treated Lily like a princess every single day, taking breaks when she told him to, walking with her whenever she goes out to buy everyone their daily dose of caffeine, taking her home and picking her up everyday on his moped and, most importantly, spending more time to help her with her project.

"Surgical robotics is amazing! Kind of scary though." Lily giggled, typing on her laptop whilst leaning on Tadashi's shoulder. The pair sat by the ledge the other day, finishing up the last few chapters of Lily's dissertation. "Not as amazing as your first robot, though." Tadashi teased, looking at the small, admittedly scary-looking, exoskeleton standing on his workdesk. Lily had managed to understand the basics of robotics while she spent time studying at The Lucky Cat Cafe and, with Hiro's help, managed to hack something simple with some of Tadashi's spare parts. It was a simple bot, playing a "Thank you, Tadashi! You're the best!" recording of Lily's voice once it's sensors were tripped. She surprised him with it a while ago one morning. The robot was still horribly primitive but it made him happy none the less. "Shut up." Lily laughed, elbowing his side.

That morning was scheduled to be Tadashi's eighty-fourth test. He had done everything specifically the night before. Fixed all the bugs in Baymax's program, rewired the circuit to perfection and tweaked a few nuts and bolts just to get that right motion. Now, it was judgement time.

Lily came in late that day, declining Tadashi's offer to pick her up that morning for the first time. Her dad needed help with repairing a few fences at the house after an accident at the Krei Tech construction that took down a part of their small garden. Tadashi, being as sweet as he is, offered to help but Lily's dad declined his offer, knowing Tadashi was looking forward to going back to the lab today. Also hating the thought of being outshined in his daughter's eyes.

Walking in the lab, amongst all the chatter and screams, she couldn't help but notice a particularly familiar cheer coming from Tadashi's partition of the lab. "Knock knock." Lily laughed, seeing Tadashi fist-pumping and dancing embarrassingly by himself on top of one of his workbenches, "What's gotten into you?"

"Lily!", Tadashi bubbled, hopping off the desk then tripping on a rolling stool as he scrambled up to Lily, "My angel, my sunshine!" He cheered, picking up her small form and spinning her in happy circles. "Hey! Hey!" Lily laughed along, Tadashi's cheer contagious. "I did it, Lils! I couldn't have done it without you!" Tadashi cheered again, still jumping around and lifting Lily into the air like a sack of potatoes. Lily couldn't stop laughing as she was now carried bridal style around the lab as Tadashi jumped and spinned almost hitting her against something. "What's going on? What did you do?" She finally said after Tadashi calmed down and/or tired himself out. "I did it! Baymax scanned me!" Tadashi panted, a huge smile still on his face as he held her close to him, "I did it. We did it. We did it, Lils."

Lily chuckled, resting a hand on his cheek as she held on to the back of his shirt with the other, now feeling just as elated as her partner. "Yeah, I guess we did."
