Prison Guard Fired

I am a prison guard and I am the only one in the whole prison. One day, due to my dereliction of duty, the criminal behind the first door escaped to another world, and I was fired. In fact, I did this on purpose. It was too boring to stay in this barren prison for thousands of years, so I directed and acted myself to give myself a vacation. Of course it was a lie that I was fired. How could I have a superior in a prison where I was alone? This novel and its characters are purely fictitious.
