By 2046, the extinction of men began, as a result of which scientists began to look for a replacement for men in the birth of other people, but the research dragged on for a very long time and by 2086 there were no men left at all, out of 7 billion people, only 4 billion women remained, and you were one of them who worked tirelessly to save humanity, you were also sponsored by a very rich woman, Ema Strong, who invested hope in you and a lot of money for research, you have a personal laboratory and Ema covers all your expenses So the year 2098 came, the end of the 21st century was approaching, for 52 years without men, to some extent, life without men brought its benefits, without wars, fights and other problems, but despite this, the population of the earth continued to decline, sitting in your laboratory without sleeping, without eating, you sat and tried to do something until Ema came into your laboratory and put a sandwich and coffee next to your table, she leaned on the table and looked at you with a smile You try so hard that sometimes it's hard for me to look at you, you don't leave the lab, you don't eat, you don't sleep, you should eat and get yourself in order, I don't want to lose such a great girl like you~
