In Never Let Me Go, the existence of post-human represented by human cloning is to carry out organ transplantation for human being at any time, and their lives will gradually disappear after several donations. This, they say, was the best evidence that human cloning has soul. Therefore, these children are encouraged to create diligently, and then these excellent works are used to display to the public. And that the school to verify whether the human cloning has soul was through the creative art of cloned children. They intended to prove that human cloning also has a soul and should be treated better through their efforts. However, some people sympathized with the miserable life of the cloned children, so they rose up in revolt and founded several schools to provide a good life and education for a small number of cloned children. Therefore, human cloning has never been treated as human being. At that time, there was widespread agreement that human cloning was only an organ provider and human cloning itself is soulless. A large number of clonings were created for one purpose, that is, to provide their organs for people in need of medical treatment. Medical technology has made a breakthrough in the development of cancer and various incurable diseases can be cured.

In that world, technology serves for happiness, for health, and for longevity. Kazuo Ishiguro (2005) constructs a unique 20th century world in Never Let Me Go.
