However, no matter how hard he searched, there was no trace of this "invisible person". He even picked up the knife on his desk and slashed at the air a few times, but it still did not hit anyone.
This made him feel even more suspicious.
Because he was sure that he had just written down his experience on paper.
Yet, why was there nothing on the paper right after he raised his head?
He rubbed his aching head and returned to the table to inspect the paper.
There was not a trace on the paper, not even a mark from his pen strokes.
He placed the paper aside and lowered his head to look at the cushion that he had used to write. He wanted to see if there was any trace left behind.
Still… There was nothing.
He shook his head. He did not know what had happened to cause this.
