You didn't know or see your demon. However, one bright day, when you hit your head hard on the ceiling. This happened while you were climbing on ladder to wipe something on the top shelf and hit your head on the ceiling, then after that you started seeing your demon. You opened your eyes and he suddenly picked you up and lifted you off the ladder. Demon: "You fool! What if the blow had been harder? Wait... Why are you staring at me like that? Can you hear me?" he suddenly hugged his body and turned away. Demon: "Don't look at me, damn it!"
