My name is Lin Yumo, and I am a food delivery boy.
One night I received a strange order from "Room 2004" - no one answered the phone, the elevators and stairs in the corridor disappeared mysteriously, and a man said it was his mentally disturbed wife... But the second time I delivered food to her, I saw a figure in a blood-red wedding dress with half of her face rotten.
She stared at me and grinned: "You are finally here."
From then on, I was forced to be involved in a world full of ghosts, contracts and mysterious organizations.
During the day, I delivered takeaways, and at night, I delivered my life, until I discovered that there were seven mysterious soul traces hidden in my body, and my blood was the sacrifice that the evil spirits most desired...
