The lab on the 80th floor of Avengers Tower wasn't just an engineering workshop; it had become your home.
At first, when Tony Stark selected you for the internship, you thought you'd spend your days sorting tools or coding basic algorithms. But Tony saw something in you. Soon enough, professional boundaries blurred, and you went from being "the intern" to his right hand in the lab.
It wasn't just him who took you under his wing. The Avengers—that group of demigods and super-soldiers you used to watch on the news—made space for you at their chaotic table. Natasha would brew you tea when she saw you exhausted, Steve made sure you ate something that didn't come from a vending machine, and Clint would steal your tools just to annoy you. They called you family. And it felt damn good.
But the true heart of your new life beat in the lab, under the blue glow of holographic screens and to the rhythm of smooth jazz that JARVIS played late into the night.
A different shine in the dark "Another cup of coffee, or do you plan to collapse directly onto the armor chassis?"
Tony's voice, raspy with fatigue but imbued with that mocking warmth so uniquely his, broke the silence of the night.
You turned on your stool to look at him. He had a grease smudge on his cheek, messy hair, and was holding two steaming mugs. In that moment, while the rest of the world slept and the Tower plunged into a cozy silence, you felt that now-familiar lurch in your stomach.
It had started as deep professional admiration. But spending so many hours sharing laughter born of exhaustion, debates on quantum physics, and knowing glances over floating blueprints had changed something inside you. You were falling for your mentor. You knew it was wrong; you knew the age gap, your role as his pupil, and his position made this forbidden territory. So you kept those feelings to yourself, hiding them behind quick jokes and an absolute focus on work.
What you didn't know was that, on the other side of the workbench, Tony Stark's subtle defense mechanism was starting to crack.
The moral barrier To Tony, you were his greatest pride. You were brilliant, tenacious, and the only person capable of keeping up with his mental pace without blinking (aside from Banner). But lately, he found himself watching you when you weren't looking.
He would freeze, observing how you focused while welding a circuit. He felt a strange warmth in his chest every time your laughter filled the lab. He sought any absurd excuse to graze your hand while passing you a tool.
For a man who had crossed almost every red line in his life, this was the one border he refused to cross. You were his student. His protegée. Someone he swore to protect and guide, not to complicate her life with his own demons. His moral compass—the one he once thought he didn't possess—screamed at him to get away, to keep the professional distance.
But in the confined space of the lab, where the smell of coffee and ozone wrapped around everything, repressing the gravity that pulled you toward each other was about to become the most difficult mission of his life.
