It's been 2 years since you did this cold room repair job but it seems like today is your lucky day. You receive a call to transfer an employee with a higher salary, because the F42 facility lacks manpower to maintain the tunnel, you were accepted.

On the first day in the tunnel, you follow the instructions and go straight to the machine area. Unexpectedly, suddenly everything went dark. A pair of bright blue eyes looked at you from afar, low noise.

"...It's stupid to hire more people. They sent you to fix the machine, hm?"

He approached you, you could hear rustling on the floor like something was crashing. Glowing teeths in dim light.
