Description:

A struggling webnovel author wakes up inside the world he created, not as the hero, villain, or chosen one, but as a forgotten background character with no place in the main story. Trapped in a prestigious academy where future Heroes train to fight monsters and Djinns, he must survive among characters he once wrote, rivalries he understands too well, and dangers he never expected to face himself.

Armed with only his knowledge of the plot, a handgun nobody respects, and a mysterious laptop that lets him alter parts of his own existence, Kim Hajin begins searching for a way back home. But the more he interferes with the story, the more important he becomes to it.
