I'm going into jail

"They will come back in the end." The prison is called the "House of the End of the World." Kim Do-yeong, the author of the book, is a prison guard who enters the prison every day. However, his workplace is not displayed on the air map and is not searched on the navigation. He cannot even carry his mobile phone. This book contains the voices of "prisoners," a job that is almost like living in a cage with an inmate, but is not under the spotlight under the huge name of "absolute security." "I'm going into jail" is a vivid testimony from an incumbent prison guard on the back of the fence.
