Kai had been trying not to look at the woman across from him for the last twelve minutes.
Not because she was doing anything strange.
She was just too aware.
Most people on the evening train knew how to disappear. Eyes on phones. Headphones in. Faces slack with the numb patience of commuters who had already spent everything useful at work.
But she kept glancing up from the paperback in her lap.
Not nervous. Not flirtatious.
Just observant.
Like she was quietly taking notes on everyone in the carriage and filing them away for later.
It made him feel seen in a way he didn't like.
So Kai looked past her instead, at the dark train window and the ghost of his own reflection layered over the city lights.
Twenty-six. Black jacket. Cheap watch. A face that looked calmer than he felt.
The reflection lied well.
His phone buzzed in his hand.
A message from his sister flashed across the screen.
Mina:Did you eat, or are you still pretending coffee counts as a personality trait?
Kai almost smiled.
Kai:I had noodles.
He sent it, then added:
Kai:Probably.
Three dots appeared, vanished, then reappeared.
Before Mina could answer, a voice cut through the carriage.
"Can you not drip that on my shoe?"
Kai looked up.
A thick-shouldered man in a gray work jacket was glaring at a teenager standing near the train door with a paper cup tilted at a dangerous angle. Coffee had splashed onto the floor during the last turn.
"It was one drop," the teenager said.
He couldn't have been older than nineteen. Skinny, curly-haired, with a backpack covered in faded pins. His voice had that reckless confidence people used when they were hoping confidence would do the work of actual strength.
"Your shoe survived."
"It won't survive your teeth if you keep talking."
A few passengers stiffened.
Nobody moved.
The woman with the paperback lowered her book slightly. Her eyes flicked from the big man to the teenager, measuring distance. Calculating.
Interesting, Kai thought.
Across the aisle, an older man with a neatly folded cane resting by his knee let out a tired sigh. He wore a dark vest over a pale shirt, and one sleeve was pinned at the shoulder where his left arm should have been.
His face was lined, but his gaze was steady.
"Sit down, both of you," he said.
His voice wasn't loud, but it carried.
"If either of you wants to die over spilled coffee, wait until the train stops. No need to involve strangers."
A short silence followed.
Then the teenager snorted.
The big man stared another second, then grunted and turned away.
"Kid's an idiot."
"Not arguing that," the older man said.
A few people laughed.
Briefly. Quietly.
The kind of laughter that belonged to trapped places and shared inconvenience.
Even the teenager cracked a grin.
"Wow. Thanks, Grandpa."
"You're welcome, Backpack."
That got a stronger reaction. Someone near the back coughed to hide a laugh.
The pressure in the carriage eased just enough to feel human again.
Kai let his shoulders loosen.
Just a little.
The woman across from him turned a page without looking down.
"That worked better than I expected."
The older man inclined his head.
"People enjoy being insulted fairly."
Her mouth twitched.
The train rattled through another tunnel section, lights flashing hard against the windows. Kai glanced at the route display above the door.
Two stops until his station.
He could make it home, shower, answer Mina properly, and maybe sleep before his alarm dragged him back into another day he didn't care about.
That was the plan.
The lights went out.
Not dimmed.
Not flickered.
Gone.
The carriage plunged into black so suddenly that several people gasped at once. The train still moved beneath them, metal grinding over tracks, but the world inside became breath and shadows and the blue-white glow of dropped phones.
Someone cursed.
Someone else laughed once, high and brittle.
"Okay. Great. That's not creepy at all."
The emergency strips should have come on.
They didn't.
