A World Where Characters Go Off Script

Pu Tong set down the character profiles in his hand and glanced toward the door. He was an ordinary high school boy from the twenty-first century, and it had been over an hour since he transmigrated here. His mission was to fix every character in this world who had gone off the rails. Incidentally, this is a danmei novel, and the reason all the characters went off the rails is the death of the key character who runs through the entire story: the protagonist's love interest.
