He told her she was complicated once.

Really? She asked back, bending over to pick up her bra from underneath his desk.

He liked complicated people. "More interesting" he said, "you're interesting to me, GoGo. A problem I can't quite solve."

Her lips remained still, and she thought she was special.

She doesn't remember how they started.

Well, not really "they." There was never a "them." They were not a couple. They did not go to dinners exclusively, did not hold hands and watch movies.

She had been working in the lab late for her newest project with electromagnetic suspension wheels. Her initial robots were speedy, and Professor Callaghan had suggested that she move onto large scale applications. Make a bike, he said. Something simple. Something flawless.

GoGo was no stranger to perfection. It had been driven into her since she was born. Her parents were sure to show her that she was not worthy of their love if she couldn't do it all. And she did, miraculously. The only thing she protested to was playing the violin. She managed to somehow scrape out of that one.

But back to the bike. Four prototypes. Four. And none of them worked well. The wheels would seem to be turning, only to collapse. It was ridiculously hard to balance both sides.

One Friday night, it was only her and Tadashi in the lab. She was grabbing yet another stick of bubble gum as he slowly exited his office. She once asked him how come he got a fancy separate space when the rest of them had to share a floor, and he responded on how he didn't want Honey's chemicals or Wasabi's laser beams to mess with his robot.

"You still up?" surprise tainting his voice.

"That's what happens when your thesis doesn't work."

He chuckled, slung his bag over his shoulder, and made to leave. Except he didn't. He stood by the door handle, silent.

"What?"

"Do you need help?"

She didn't say anything to this. Help? Asking people was a weakness.

Well, Tadashi was a weird one, because he took her silence as a yes. It wasn't long before that bag of his was slung next to her, and he crouched down to look at the bike.

"The balance is off."
"I know that."

"Have you tried moving the magnets from the top," he reached over, pointing, "to the middle section here?"

"I…"

She wanted to say that she's tried everything, dumbwit, everything but moving the magnet location, and oh god now it makes sense, of course it freaking does, and do you know that your elbow just brushed over my chest? Because it did, and I noticed it.

GoGo says "I didn't think of that."

And so late Friday nights became a tradition. He would show up with two coffee cups around eight, she would offer him some sticks of her sacred bubble gum. When his office door opened, she came to expect his voice calling her name, her nickname, anything to come test out Baymax. On some days, his prized creation would be able to tell her bodily functions with ease. Other days, not so much.

"Why is programming so hard?" he exclaimed one day, nearly slamming his face into the desk with exhaustion.

"If it was easy, anyone could attend SanFranskyo University. And that would suck."

"More minds, more ideas."

"…less workspace."

He cracked a smile at this one. "I like the way you think, GoGo."

It was one of the few times he had used her real name since they had met. It was also one of the few times that he complimented her on something that wasn't work related.

Something must have been off in the expression of her face, because his smile slowly faded.

"Sorry, I didn't mean to make you uncomfortable."

"You're fine." She curtly replied.

But she wanted to say how much she wanted to drag his face to hers. How this tension had been building between them, and they both knew it but neither wanted to address it. How even the janitors were gone at this hour.

"Let's try out your stupid robot again." Is what she actually said.

The first time they did it was when her bike finally worked.

It wasn't fast, yet, but she couldn't help and smile at the smoothness. It was like she was sailing around the lab.

When she finally slowed down to a stop and took off her helmet, she was captured in a huge hug.

"You did it!" he laughed, spinning her around.

When he sets her down, there is a pause. Tadashi's smile, the sun's radiation in human form, is directed towards her. Only her.

Without thinking about it, GoGo leans forward to kiss him.

It is both how she expected and not how she thought it would go. He is as gently as she thought, his hands first resting at the sides of her waist before slowly caressing up to land on her breasts, his fingers brushing against her nipples. However, as soon as she makes it clear that she has no intention of stopping, his actions grow bolder. He picks her up and nearly slams her down on the nearest workbench. His mouth moves everywhere, but she can still feel his smile as he engraves his teeth into her skin. It is rough, but not careless. Her shirt comes off first, and then his signature hat. She thanks some deity that she wore a sports bra with a front zipper that day, and keeps her dark eyes against his as he slowly pulls it down. Once it is open, he descends his face to praise her chest, getting bolder by the minute. Eventually, his tongue finds a nipple and GoGo has to scream.

The rest of the clothes came off easily after that. When he finally enters her, there is a sigh that escapes from both of them, like finally collapsing into a couch after a hard day's work. But instead, Tadashi is collapsing into her, she's never felt so full and complete in her life. She wraps her short legs around his naked waist, lets him buck into her at his pace and tries to ride him for all that he is doing to her. Within minutes, she can tell he is close. Instead of pushing him away, she grabs him closer, claws at his neck and back and arms with her short nails.

Suddenly he lets a hand drift between them, and she is all over, careening and wanting and building. She feels crazy, feels mad with desire, grabs her face so she can whisper things in his ear that she never meant to say, words like how much she wanted him, needed him, how she didn't want him to stop. "Fuck me," she rasps, not even feeling bad in the slightest for the noises she was making, for the sweat on his brow. Within seconds she bursts, spasming all around his hard length, and then all of the sudden he goes faster, as if he was holding back for her benefit. GoGo doesn't care, she just holds onto his hair as her thighs dig into the counter top, as she mewls his name into his ear. She grunts when he finally finds his release, and he marks her neck as his.

The next day, Wasabi nearly has a heart attack when he finds all of his tools in disorganized piles. He gruffs at the two from across the lab, asking how they managed to forget to pick up the pliers from the floor.

Tadashi just offers a sheepish apology while GoGo carefully readjusts her scarf.

They do this for months. At first, the tension between them an all-time high. They spend enough nights alone in the lab for GoGo to believe that their tryst really was a one-time miracle. It isn't until nearly three weeks later, when she reaches down to pick up a fallen wheel, that she turns around and finds Tadashi, coffee cups in hand, eyes dark with predatory intentions.

That night, they had opted for his desk instead, the windows wide open as he took her from behind. She screamed her pleasure out to the empty San Franskyo University gardens.

She hasn't had much experience with sex but she has done enough to know that Tadashi treats her well. Her needs are always satisfied, the after-care is always reliable. In predictable prepared-Tadashi fashion, he begins to leave towels and spare changes of clothing in his office. Just in case.

GoGo wasn't quite sure of what she wanted. She was never the romantic type, didn't understand how flowers and teddy bears were supposed to make you feel warm inside. The things that did make her breathing constrict around Tadashi were different. She didn't need a prince on some white horse. This guy, covered in grease, baseball cap and smile, made her think about white dresses. About more nights spent with robots and machines. About growing old.

Every time they came together, she let herself need him.

So it was only natural to believe that he wanted her, too.

It isn't until one day, when she is writing up her thesis on her laptop, when she hears an explosion from the other side of the lab.

Everyone is startled, but it is Tadashi who slams open the door to his office first; Tadashi who rushes over to Honey Lemon's side, who lifts her unconscious body and carries her to the nurse's office.

From then on, it seems natural that Honey Lemon work with someone else, just in case. And who better to help supervise than the robotic inventor? Baymax was nearly complete—he only needed to be tweaked in cosmetic design. Soon, GoGo would find herself going home early on weekends, since her project was wrapping up too.

Tadashi was…he was the kind of guy who always helped others. Always.

One Friday, she comes back to the lab to pick up a forgotten USB. The door opens but she immediately closes it softly, heels turning away. But it is too late. She saw the yellow that leaned into him, saw his cap that had fallen to the floor because of her manicured hands in his hair. It wasn't even a compromising, dirty situation, but GoGo knew Tadashi well enough to know that they had never kissed like that.

She no longer stays over late, and Tadashi no longer looks at her. She can only watch as the two lovers bloom, as they blush over stolen moments in between work. She can only eat her food as Wasabi and Fred discuss their suspicions about the two during lunch break. Her throat clenches as she remembers how no one had ever gossiped about her and Tadashi. And for good reason.

Woman up, she thinks. And life goes on.

"Welcome to the nerd lab."

She watched the younger Hamada's face scrunch up, but he quickly wanders over to Wasabi's station. Her first encounter with the boy is quickly forgotten when she sees Tadashi lingering behind, looking at her strangely.

His big brown eyes are killing her. The bubble gum in her mouth tastes sour.

"What?" she eventually spits out.

He looks like he wants to say something, but he decides against it. "I'm sorry," is all he says.

She turns away. "'s okay, Tadashi. I know you're a good guy."

Before the awkward silence stews any longer, she walks away to go steal a wrench.

Work was an essential distraction.

Tadashi's death was….

GoGo breathes sharply. Tadashi's death. Tadashi died. He was gone.

Her first sensation back to reality comes from Honey collapsing beside her to the ground. The rest of them are frozen, looking at the falling, burning building, the firefighters who hopelessly spray the flames.

She is the second of the group to notice Hiro. First was Cass, who sat down next to him on the ambulance edge, crying while clutching his head against her chest.

However, Hiro's arms do not wrap around his aunt's, and when the woman is finally dragged away she notices tear stains but no tears. The baseball cap is enclosed in his arms, his eyes wide and empty.

It strikes her, how much he reminds her of when she was twelve and her father drove away for the last time. How her mother had cried and then opened the liquor cabinet.

How she grabbed the violin she got for her birthday and threw it out the window.

From that day, to the wake, to every time they went over to the café, her eyes would be drawn to him. This angry, destroyed boy.

And it was some sort of beautiful to know that she wasn't alone, that someone else also had their sun taken away.

She thinks she's kind of messed up.

She feels like she is the first to notice that Hiro has grown up.

First, it was his height. She was used to people growing taller than her short frame, but it still surprised her when this kid brother of Tadashi's suddenly popped up behind her when she tried to put up a box of parts into storage.

"Thanks," she muttered as he finished pushing in the box for her.

"No problem," he replied, and he continued searching for whatever he came here for, Baymax waddling right behind him. The rest of the group finally noticed when Hiro competed with Fred for height. They all laughed at the idea that he might one day surpass even Honey Lemon's lithe frame.

His hands were next. Whether they were in the lab or out to lunch, she couldn't help but notice how he would hold a screwdriver or his chopsticks. Delicately. For all of his rough edges, Hiro had the precision of a surgeon when it came down to his work. Especially the new microbots that he was adjusting to his suit for combat. He had showed them to GoGo one day.

"Look! They're controlled with a neurostimulator I put in my helmet. However, there's only a few "programmed" modes."

It was true. Hiro suddenly had a full set of tools he could use while on the back of Baymax. It was quite clever. GoGo had asked why he hadn't made it so the bots could turn into a weapon, and he replied that he didn't want to use his inventions for violence.

She wonders whether her attraction to him is based on revenge or if she is actually attracted to someone six years her junior. She decides after waking up to a third dream full of gap teeth and hard flesh that it is the latter. Disturbing as it is, she makes up her mind not to dwell on it too much, but fails miserably.

When he congratulates her on her next invention, a car that uses wind power instead of gasoline, he swings her in the air like she weighs nothing. Months of noticing his height, his hands, his big goofy smile that was even starting to look not-so-stupid, accumulates. She is transported to another time, another invention, another Hamada.

She knows not to kiss him this time.

Of course, Hiro is not Tadashi.

For one, Tadashi would never imagine outfitting Baymax with new gear every few weeks or so. The robot's core health-service programming was being mass-produced and distributed among hospitals, just as the late Hamada would have wanted. But the visual design was much different, a harder-steel type thing that Hiro had asked the rest of them to help him develop.

GoGo had once asked why the re-design was necessary. Baymax was unique, Hiro had told her. That was surprising. Tadashi had never seen the personality of the robots he designed. They were all tools, meant to help humanity, but cold things made of metal and one and zeros instead.

To Hiro, Baymax was family.

Hiro was also not Tadashi in that he didn't pretend that everyone was equal in his eyes. Sure, the six of them were as close as a friend group could be. But it became obvious over the years that he tended to gravitate towards Baymax and surprisingly, GoGo. Especially when it came to work. She would learn about the latest gadget or microbot application he had come up with often days before he revealed it to anyone else. It was an honor.

Finally, Hiro was a closed book. Sure, he was outgoing enough. He got excited over even the slightest advancement. He was visually depressed when hours of work amounted to nothing. But GoGo noticed something else was there. She didn't know what it was, and that bothered her. At least her deceased ex-lover was obvious in his intentions. There were no guessing games with how Tadashi felt.

Hiro had mood swings nearly every week. She almost felt that it was her duty to notice the little things about him, to analyze and crack his actions. Chewing on a pencil meant new ideas. Making a paper-clip chain meant he was bored.

And yet she could never figure Hiro out completely. She started wondering if she really wanted to.

It is when he is just 19, after they go out to dinner to celebrate his acceptance into the university's graduate school department. After eating at the best sushi shop in town, they settle down in the garage to watch some old school karate movies with Baymax, who unfortunately wasn't allowed to attend the meal ("I am a robot. I do not need to eat." Assured Baymax).

Around one, everyone begins to leave. GoGo is contemplating whether to stay or risk becoming too lethargic to leave later.

Since no one else was there, they had the whole couch to themselves. GoGo has her head resting on one arm, her legs overlapping with Hiro's. They mindlessly stare at the screen as Bruce Lee whips around his nun-chucks.

She feels eyes on her, so she turns towards him instead.

"What?"

"I've never seen you this dressed up before."

Her eye brows raise, but it's true. The sushi place they went to was pretty high end, so she pulled out the only nice thing she owned, a dark blue suit complete with matching pencil skirt. Right now, the jacket hung on the edge of a computer chair, and her white blouse was opened to a few buttons to combat the humidity in the garage.

"Even I know how to dress for nice places, idiot." With this, she tries to bop her stocking-covered foot on his chest. It is meant to be teasing, light.

She doesn't miss the way Hiro's eyes go wide and race back to the T.V. screen. Her curiosity piqued, she looked at the rest of his body. Face flushed. Adam's apple bobbing.

Barely noticeable bulge in his dress pants.

Something comes over her. Her foot seems to move on its own, dragging from his chest up to his swallowing neck and to his face. She turns his cheek towards her, not like it would have mattered anyways. Hiro has forgotten the program entirely.

She speaks first. "Baymax, go charge."

The robot seems to understand, and keeps silent as it docks into his station and deflates quietly.

She sits up and crawls over to his side of the couch. His breathing is irregular, his eyes seem to drift from her face to her chest back to her face. He sputters out a "…Why me?"

GoGo is silent at first, placing his hands on her hips. He shudders when her fingers roam over his legs, his abs, resting on his chest.

"You are complicated," She replies, grasping his tie to pull him to her lips.

"And that makes you interesting."

A/N: I'm back. Inspired by watching this movie the second time tonight, but started about a month ago. Might get a second part. Reviews and critiques welcome.
