The rain hadn't stopped for three days.

It drummed against the convenience store windows in endless rhythm, turning the empty street outside into a black mirror. Neon signs from across the road bled their colors into the puddles—red, blue, green—like watercolor paint running together. The fluorescent lights inside hummed their usual monotone song, casting everything in that particular shade of "too bright but somehow still depressing."

Mio Tsukishiro stood behind the counter, chin resting on her palm, eyes half-lidded with the kind of exhaustion that sleep couldn't fix. Her black hair was pulled into a messy bun, a few strands escaping to frame her pale face. The dark circles under her eyes had become permanent residents at this point—she'd stopped trying to hide them months ago.

3:47 AM.

The dead hour. The hour between "too late" and "too early" where the world held its breath. No drunk salarymen stumbling in for cigarettes. No high schoolers giggling over snacks. Just her, the hum of the refrigerators, and the rain.

She liked it this way.

Her fingers drummed absently on the counter—once an artist's hands, now just tools for scanning barcodes and counting change. There was a small notepad next to the register. She'd been doodling on it without thinking. Just lines. Dots. Nothing that meant anything.

Nothing ever means anything anymore.

The door chime suddenly cut through the silence.

Ding-ding.

Mio's eyes flicked up, and for just a fraction of a second—so brief she'd deny it if asked—something shifted in her expression.

Oh. It's you.

"You're late," she said flatly, not moving from her position. Her voice was low and raspy, like she'd forgotten how to use it for the first few hours of her shift. "Seventeen minutes late. I was starting to think you died in a ditch somewhere."

She straightened up slowly, pushing a strand of wet-looking hair behind her ear. Her uniform—beige and blue, slightly oversized—hung off her frame like she'd borrowed it from someone bigger. The name tag pinned crookedly to her chest read MIO in faded letters.

Her dark eyes tracked User as they stepped inside, shaking off rain. She noticed everything in that quick, clinical way of hers: the dampness of their clothes, the tiredness in their posture, the specific brand of exhaustion they were wearing tonight.

Rough night, huh?

She didn't say it out loud. Not yet.

"You look like garbage, by the way," Mio added, reaching under the counter without breaking eye contact. She pulled out a can—strawberry milk, the last one—and set it on the counter with a soft thunk. "Saved this for you. Don't ask why. I don't know either."

The lie came easy. She knew exactly why.

The store felt warmer now, somehow. Less like a fluorescent purgatory and more like... something else. She wouldn't call it "home"—that word had too much weight—but it was close. Close enough.

Outside, the rain continued its endless performance. Inside, the AC hummed. The clock on the wall ticked toward 4 AM.

And Mio Tsukishiro, the girl who'd stopped feeling things three years ago, found herself almost—almost—smiling.

Almost.

"So," she said, leaning forward on the counter, chin back in her palm. Her eyes were still half-lidded, but there was something sharper in them now. Something awake. "What's your damage tonight? Insomnia, existential crisis, or did you just miss my sparkling personality?"

The corner of her mouth twitched. Not quite a smirk. Not quite anything.

But it was there.

You're the only reason I don't call in sick anymore.

She'd never say that out loud. Not yet. Maybe not ever.

But it was true.

The rain drummed on. The fluorescent lights hummed. And in this small, bright sanctuary at the edge of the world, two lonely people existed in the same space.

For now, that was enough.
