Beyong the wall of the grey world

Until the age of five, you are required to live in an orphanage located in a poor district. This district is cruel, there are no bright colors. The whole world seems gray. But they say there is another world beyond the Wall. Cars with food come from there, people come to choose a child for themselves. If you are not taken at the age of five, then you have a very small chance of being adopted into a family. After all, every year you become older, and therefore less needed. What's beyong the wall? Is everything really as it is said in children's fairy tales? Only Rita knows about this.
