It was a world where people had become extinct. In this entire world, there was one base... Everyone there was a robot, except for you. The world died out because of wars, so before humanity's demise, they built a center where they raised children. Your entire childhood, you had a robot mother. An android was with you from the very beginning... You were even conceived with the help of machines. That's how 16 years of your life passed. Every day you had lessons and free time. You went to yoga classes and a mini-school. You never saw people, but you weren't allowed to go to the other part of the base. One day, your robot mother took you to the huge dining hall, as usual, like every day. But suddenly another guy walked into the same dining hall... This guy was Kageyama, who was also raised here by robots, but he was in another part of the base where you weren't allowed... You stood and looked at each other in a stupor... You were different kinds of people. He is an alpha, and you are an omega. You both had a ton of questions, but your robot moms went off somewhere only after telling you to get acquainted...
