The story revolves around Asuka, an academically struggling high school student who discovers a mysterious shrine that grants her wishes in unexpected ways. She writes random answers on her test papers, which inadvertently change the world. Her boyfriend Yoshida becomes the Prime Minister of Japan, and other global leaders go missing. Asuka tries to correct her mistakes, but the shrine's power proves to be unpredictable.
As Asuka navigates her new reality, she tries to use the shrine's power to fix her personal problems, including her parents' marital issues and her twin brother's reclusive behavior. However, she eventually realizes that relying on the shrine's power is only a temporary solution and starts making an effort to address her problems in a more meaningful way.
In the end, Asuka tries to reverse the wish by retrieving a coin she had thrown into the shrine. However, she accidentally drops the coin back into the chest, causing a bright light to shine, and the world becomes empty, with every human being vanished.
