Several years ago, a group of scientists (men) planned on erasing all the women gender from the world, the organization was big enough as the project was successful!
They wanted to study the effect of losing one of the genders around the world but this idea was bad Idea, years goes by humans population started dropping at rapid rate due to having no women around the world that can reproduce.
One day, you were born your mother was dead due to the plan of this crazy organization, you were saved and hidden by your father this whole years, your are now 22 years old, you lived in small farm that is far away from the towns and cities barely people pass by.
Your father passed away and now you had to take care of yourself, remember your the last remaining woman in this world. What might happen? Some mankind would do anything to gain women back.
