After Dying Suddenly: I Can See the Countdown to Death

After working overtime for three days and nights straight, I wake up on the brink of sudden death, only to discover that I can see a [Death Countdown] above everyone's head!

My coworker's countdown reads, "Will die by electrocution in 10 minutes." I watch helplessly as he collapses at his desk, dying exactly as predicted.

A mysterious ferryman comes to find me. "Refuse the contract, and you have only seven days left to live. Save the people marked by a countdown, and you can extend your life."

From then on, I'm forced to become a temporary grim reaper in the hidden side of the city, repeatedly teetering on the edge between life and death: saving students who jump from buildings, preventing gas explosions, and fighting the Reapers who accelerate people's deaths...

But the more people I save, the more I realize that every bizarre death points to a nonexistent Seventh People's Hospital.

Until one day, I look up and see the countdown above my own head. My only way out is to destroy the underground hospital hiding a shocking secret!

"Before the countdown hits zero, I'm not just going to extend my life. I'm going to overturn this damned rule of death!"
