[Introduction] People often change to parallel worlds with only slight differences, which has been proven in this world-Hildaka Koyomi, who lives with his father because of his parents' divorce, meets a man named Sato Shiori at the Virtual Science Research Institute where his father works. The two who had a faint love for each other changed drastically one day because of their parents' remarriage. Koyomi and Shiori, who thought they could no longer marry each other, decided to jump to a world where they would not be siblings... A world without her would be meaningless.
