I Rely on Writing Leave Requests to Survive in the Apocalypse

My name is He Bi, and I was a copywriter before the end of the world. On the third day of the apocalypse, a corrupted titan thrust its claws into the air-raid shelter where I was hiding. More than a hundred people ran away in fear. I squatted in the corner and took out a notebook. Write a request for leave to the monster. Reason: I haven't showered in three days. It was granted leave. It ran away. I thought this matter was over. Until the next morning, someone knocked on the door: "Is Mr. He Bi here? Yesterday, the Titan said that you can approve leave?" I open the door. There were more than twenty monsters standing outside the door. Queue up. This novel and its characters are purely fictitious.
