It is the first collection of short stories in Gangnamju, and contains nine works in total. These works consistently look at the old age problems faced by Korean society with a calm and firm perspective. The appearance of old age in our time, drawn with realistic materials and a style without exaggeration, resembles the main character of the title work, which is now isolated and has a separate room while no one is paying attention.

The main axis of the story is a number of conflicts that begin when an elderly couple uses a separate room. The elderly couple in the novel use each room for a while, and after accidentally watching the news of their sudden death, they decide to share a room again. It is sad to say that the reason for the union of a couple who have lived together for most of their lives is to prevent death, but the novel eloquently says that it is a problem that many elderly couples are actually facing.
