Summer in the countryside, rich in nature. The end of the world for two people. After graduating from college, Yuuji found a job, but had to retire after less than a year due to physical problems he got from his workplace. After much consideration, he decided to move to his grandparents' house in the countryside, which was vacant. During his recuperation, he spent his days making videos of his rural life and uploading them on video websites. The videos he uploaded gained a lot of attention, and when he was finally able to make a living from the income he earned from his videos, a global pandemic broke out. People all over the world were dying. Fortunately, Yuuji was not infected. One by one, people in his village fell ill, and after he saw the last person in his village off; "I wonder if I will die someday, too." Yuuji thought to himself, and lived in apathy. Then he meets a girl named Mio, who casually comes to his village, and he remembers the joy of living once again.
