Steve Rogers and Tony Stark
Steve x Tony late night at lab3 AM in Avengers Tower
Steve couldn't sleep. Again.
The silence of his room felt too heavy, so he wandered the Tower—only to find the lab lights still on. Of course. Tony never slept either.
He hesitated at the door. Part of him wanted to turn around. But the other part—the part that ached whenever Tony pretended not to notice the tension between them pushed him forward.
Tony didn't look up when the door slid open. "JARVIS, mute the alerts, I'm working—"
"It's me," Steve said.
Tony's hands froze over the holograms. For a second, Steve swore he saw something flicker in his eyes. Surprise? Greed? Before the usual mask slid back. "Captain America, breaking curfew?" Tony spun in his chair, grinning. "Scandalous."
There it was again that pull. Like gravity. Tony's laugh, the way his shirt rode up just a little when he stretched, the oil smudge on his cheek. Steve rolled his eyes but stepped closer. He had to away, face heat up, jaw tight, heart pounding like he'd just run a mile. By the time he gathered the courage to glance back —
Tony was already turning back to his work, shoulders tense. Steve grabbed the spare stool and sat. "What're you building?"
Tony blinked. "Since when do you care about my tech?"
"Since... now." Steve muttered, suddenly feeling awkward. His fingers tapped restlessly against his knee.
