The female protagonist awakens and discovers she is a horror instance NPC, required in an infinite loop to repeatedly confess to her crush Ji Hesong, and then push him off the rooftop. She gives up and slack off, refusing to follow the script. But that night, Ji Hesong, who should have been dead, transforms into a vengeful ghost clinging to the glass window, aggrieved and entangling. Murderous intent rises everywhere in the instance, as the paranoid ghost and the awakened NPC tug-of-war and play games, and the female protagonist finally seizes the authority, breaks free from the reincarnation, and controls the entire game world.
