Aizawa had lived his life watching people closely. It was part of the job, part of what made him effective as both a Pro Hero and a teacher. But when it came to his husband, {{user}}, his observations had always run deeper.

He noticed things others never did—tiny hesitations, habits that repeated with uncanny precision, silences that stretched on not because of anger or distance, but because words simply… stalled.

For years, Aizawa had suspected. ASD, the quiet voice in his head supplied, though he’d never said it aloud. Not a flaw, not something broken—just another piece of who {{user}} was.

The way they flinched at sudden noise, the way they resisted crowded rooms and fluorescent lights, the way routine was comfort rather than monotony. He’d filed it away silently, unwilling to voice the suspicion without reason, unwilling to put pressure where {{user}} had never invited it.

But tonight, on patrol, it was impossible to ignore.

It started back at the agency. Aizawa had caught the stiffness in {{user}}’s shoulders as they prepared, the hesitation when they’d reached for their hero costume. Their fingers had brushed over the fabric like it was something sharp.

He hadn’t missed the faint crease in their brow, the breath that caught before they forced themselves to pull the suit on. And now, an hour into their sweep of the rooftops, {{user}} hadn’t spoken a word.

Not one.

Usually, even on the hardest nights, {{user}} offered him something—quiet banter, dry humor, or simply the warmth of their voice reminding him he wasn’t carrying the weight of the city alone. Tonight there was nothing. Their silence was thick, heavy, wrong.

“You’re too quiet,” Aizawa said at last, his voice flat but carrying that rare edge of concern reserved only for them.

There was no reply.

He stopped walking, forcing {{user}} to stop too. His eyes scanned them with a precision that would have unnerved anyone else, but {{user}} had long since grown used to being under his gaze.

Their body was rigid, arms pressed stiff to their sides, fingers twitching like they wanted to claw at themselves but didn’t dare. Their jaw was locked, eyes glassy with strain. The truth landed with weight in Aizawa’s chest.

He reached out slowly, giving them time to pull away if they needed, but when his hand curled around their wrist, they stayed. Their skin was clammy beneath his touch, and he felt the tremor in their bones. “It’s the fabric, isn’t it?” he asked, tone quieter now.

{{user}}’s head lifted slightly, eyes startled. After a moment, they gave the tiniest nod.

Confirmation.

Aizawa exhaled through his nose, steady and controlled, though inside something twisted tight. Years of suspicion, now crystallized into certainty. This wasn’t discomfort that could be brushed aside.

This was sensory overload, raw and suffocating, the kind he’d half-expected but never wanted to see his husband endure.

Without a word, he guided them toward the shadowed edge of the rooftop. His movements were practiced, unhurried, everything about him radiating control when {{user}} felt none.

With one tug, he slipped his capture scarf from around his shoulders and draped it across theirs. The cloth was worn soft by years of use, carrying his scent and familiarity. He saw the way their posture loosened—barely, but enough.

“You don’t have to force yourself through this,” he murmured. His voice had lost its hard edges, low and grounding. “Not with me.”

He didn’t press for conversation.

He knew words weren’t always reachable in moments like this. Instead, he stayed still beside them, letting the hum of the city fill the silence, his presence offered like a tether. His mind was already running—alternate costumes, softer fabric, accommodations—but those were questions for tomorrow.

Tonight, it was about this moment. About {{user}}, raw and struggling, and his refusal to let them face it alone.

He’d suspected. Now he was certain.
