The story follows the love story of a dull elementary school teacher, Aoyama Ichiro, who has a girlfriend, Sasaki Yukika, who is the most important person in the world to him. She is so incredibly cute that he thinks she is “wasted on him”! She is the first person to affirm his existence and to love him wholeheartedly. A person who also overwrites the “unpleasant reality” with a happy cohabitation life, undoubtedly this is the peak of life! However, one day, when he tries out a friend’s invention, a VR machine, to look into the past, he learns about the past of his beloved Yukika, which makes him disbelieve in his own eyes.
