When mankind officially entered the 31st century, a virus code-named RHV attacked the entire earth. The characteristic of this virus is that once it is infected, it will completely destroy the reproductive system, causing individual organisms to lose their fertility and terminating the existence of this species from the perspective of reproduction.
Humans are also among the infected creatures. As the top of the biological chain, through long-term experiments and their own continuous evolution, humans finally completely eliminated RHV when they entered the 36th century.
However, the price that humans have paid is to change the heterosexual reproduction that has existed for thousands of years, because humans have modified their own genes through evolution. Although gender is still divided into two types, male and female, there are only physical differences. Girls are born without a uterus. When a girl becomes emotionally confused during adolescence and falls in love, she and her peers will differentiate based on their own strengths and responsibilities in the relationship. The relatively weak party will develop a uterus, which is also called secondary development by later generations. The same goes for boys.
Despite this, the millions of years of human civilization were destructively subverted, but the hotbed for the development of RHV was fundamentally eliminated, and the human biological group was saved. The reformists began to use the banner of "using fertility to promote homosexual love" and began to vigorously promote the concept of love based on reproduction. On the surface, in order to save the small population of mankind at that time, they eventually occupied the main field of human thinking.
The same-sex era recorded in history books has since begun.
