I remember that the shortest science fiction novel in the world is "The last person on earth was sitting alone in the room, and then suddenly there was a knock on the door..." But what if there is not just one person left, but several people?
Will these people bring out the best in human nature, or will they concentrate the worst?
Adam and Eve are the ancestors of mankind, but they have never been happy, and no one cares whether there is love between them. They are just tools to perpetuate the human race.
When people are reduced to tools, it is too luxurious to talk about feelings.
