On the first day of transferring school, Zhou Ye discovered a door on the back wall of the classroom. He is the only one in the class who can see it.
The next day, the classmate in the next seat disappeared. No one remembered that he existed - not the teacher, not on the roster, and even the parents forgot that they had this son.
Monitor Lu Miao is the only one who believes in him. Her grandfather died in a "fire that no one remembers" ten years ago, leaving only a jade pendant that can be heard behind the door. History teacher Shen Zhuo was lame in one leg - seventeen years ago, he watched his student Han Mo being dragged in by the door, and his right leg was severed by the door.
The old scar on Zhou Ye's wrist began to feel hot. Shen Zhuo told him: That is not a scar, but a "door seal". This isn't the first time you've stood in front of it.
The door in his dream has been opened three times. Each time, someone died on his behalf.
But this time, there are not only forgotten people behind the tenth door.
There is also a pair of eyes that have seen for thousands of years.
