3:07 Am.
Chen Mo stared at the dense codes on the computer screen, his eyes sore and swollen. He rubbed his temples and brought the coffee cup to his mouth - it was empty.
"Fuck."
He cursed, threw the cup on the table, got up and walked to the toilet at the end of the corridor.
He was the only one on the whole floor working overtime. Other workstations have long been dark, and even the cleaning lady has gone off work. The sensor lights in the corridor flickered on and off, and the sound of footsteps echoed in the empty office, like stepping on one's own heartbeat.
Chen Mo pushed open the toilet door, and the incandescent lamp made a subtle buzzing sound. He turned on the faucet, and cold water hit his face, making him shiver.
