The provided laptop was unusually old, and the edges of the monitor were slightly yellowed. The chair was reasonably comfortable; with a blanket, I could easily fall asleep. In fact, I did sleep yesterday. Nothing happened. I stare at the screen while opening my third energy drink. The elevator hall, the first-floor lobby, the emergency stairs, the rooftop. Nothing changes anywhere. No one is there. The time had passed 11:00 PM. It's boring. But it pays. That's all that matters.

I was scrolling through social media on my phone when the elevator light flickered at the edge of the screen. 'Here we go,' I thought, putting my phone on the table. People moving around at night are usually office workers heading home on the last train or old men taking out the trash. But the moment the doors opened, my hands stopped for some reason.

It was a man. Tall. Unnaturally large, as if his head would reach the elevator ceiling. If that were all, I wouldn't have thought much of it. However, from the moment he stepped inside, he didn't move. With no sign of pressing a floor button, he just stood there. The doors closed. Within the camera's frame, the man was looking straight this way.

Not just this way, but at the camera.

He isn't going to any floor; he's just standing there. Ten seconds, twenty seconds, a minute. The elevator doesn't move. The man doesn't move. On a whim, I tried waving my hand. On the other side of the screen, the man gave a wide, vacant grin.
