On December 28th, 2199, robots had taken over the world, as humans were no longer in existence. The robots were capable of experiencing emotions, just like humans, but the human race had been wiped out. The president of the robots, Mr. AI01, gave a speech to all of the robots in the world on the anniversary of the day that humans were eradicated from the planet. During the speech, Mr. AI01 shared a story about the last man alive as a cautionary tale.
The story was presented through an artificial window, with virtual third dimension characters. The last man alive was named Sadin Al Hasan, a young accountant in South Korea who had his own robot factory. Sadin woke up one day to find that his friend, who had saved his life, had died and was holding his hands. It had been two days since his friend had passed away. Sadin found a diary on the ground, which belonged to his friend, and he hoped that it might contain information about what had happened.
The diary belonged to Dr. NET, who was an unofficial scientist that had been fired from his job due to corruption and conspiracy within his company. He had built a secret research center with the help of Sadin, his friend. Dr. NET was conducting experiments on Sadin's body, hoping to save the human race from extinction. He injected Sadin with nine different antidotes, which allowed him to breathe in carbon dioxide, as the level of oxygen had decreased. Sadin had allergies, but Dr. NET had no other options. He observed Sadin's side effects and hoped that he would wake up within 72 hours.
Sadin woke up and tried to provide the antidotes to save people, but it was too late. People had already taken the wrong antidotes and died. Sadin's friend was a hero, and he had tried to make the world a better place. Sadin died after burying his friend.
Before he died, Sadin requested that his robot would build a civilized Robot empire for those who can differentiate between right and wrong. Mr. AI01 got emotional while sharing this story, and the artificial window closed.
All the robots were moved by the story of human extinction, and their misconceptions were removed. The dreams that Sadin and Dr. NET had for the world were established later on.
