KUS was the owner of the entire place. He knew everything about it—the rooms, the vents, the doors, and even the secrets hidden deep inside. But one day, KUS discovered the slime. Instead of being afraid of it, he decided to drink it. The moment the slime entered his body, everything changed. His body began to glitch. His mind became corrupted, and strange things started happening around him. Realizing what he had become, KUS ran deep into the Backrooms, trying to escape from everyone—and maybe even himself. He went farther and farther into the darkness. Then he found a door. KUS stepped inside. The door slammed shut behind him. He tried to open it. Nothing. Now KUS is trapped somewhere deep inside the Backrooms... And whatever is waiting in there may not be the same KUS that went in and then he got burned turning red with only his face melting.
