Hiro Hamada, robotics prodigy had been asked to attend a meeting with Tony stark. And you being the daughter of said man, had to accompany him(because of also said man forgot that it was your birthday).

So you had been on the jet in the back, headphones on, music blasting, as you mapped out your latest design for the suit your dad had promised he'd assemble once he proof read your blueprints, when Hiro shyly popped his head in the jet.

You hadn't noticed at first until there was a light tap on your shoulder. Thinking it was your dad, you sigh.

"What? You said you wouldn't bother me until I've finished."

There's another tap, and the curved line you had been drawing flattens out. Ripping off your headphones, you look up to give Tony an earful, but there's a boy about your age standing there looking helplessly embarrassed.

"H-Hi."

"Hello..?" You've never actually seen a picture oh Hiro Hamada, but as your father had put it, you'd "know it when he gets there". "You're-"

"Hamada Hiro," He rubs his neck with one, and you then notice that he's carrying a red metal box. "I meant Hiro Hamada."

"Yeah," You say, grabbing your eraser and fix the misplaced line. "I figured. My dad'll be here in about.. actually I don't even know. He's late to everything. Best word of advice, don't do business with him."

He's silent as he stands there, trying to secretly look over your shoulder at your designs when he gasps. You jump, turn, and snap what right before he plops down next to you and hands you the box.

"This is so cool," He murmurs, sliding your blueprints closer to him and you fumble with his possession in confusion. "I've never seen something like this before. It's so.."

"Lame?" You set the box on the table and snatch the papers back. "Yeah. My dads already told me that-"

"No," he shakes his head, points to where you had left off. "You're on the right track, you're just missing something."

"Yeah," You snort. "I'm missing the rest of the body piece."

And then it turns into an all out discussion of the design, the pros and the cons, how to make it better, what's actually missing beside half of the suit.

"Piece of cake," Tony says to Natasha, who starts the engine on the jet and prepares for take off. "Get young, smart boy on the plane with my daughter and the first thing they do? Talk about robotics. I'm so proud."

Natasha rolls her eyes as Tony wipes a fake tear. "Yeah, you'll be saying that when they want to build an actual robot. Remember what happened last time you did that?"

Tony's eyes widen. "Uh oh."
