Doomsday: I Am Not the Savior

I am an ordinary online ride-hailing driver. By chance, I took a strange order to deliver a mysterious suitcase. On the way to transport, I encountered many terrifying man-eating monsters. The streets were full of these monsters, and they were all transformed from humans. In order to avoid them, I had to stop delivering boxes and go home to hide. Unfortunately, I was bitten and opened the box by mistake. I survived, but am I still human?
