Futawata Shinori is part of the "nobodies" in school but she is secretly dating popular guy Suga Misaki. However, she also has a secret which she hides from everyone - she is the owner of popular social media account "Shirousa" (white rabbit). One day, Shinori and Misaki had an argument and Shinori wished that her "online life" becomes real. The next day, Shinori realised that everything around her becomes weird and she can't find Misaki anywhere. Misaki also noticed that Shinori's existence in the world is gone. Shinori later found out she got stuck in a parallel world where the students' popularity is ranked based on their social media accounts, thus causing Shinori to be a popular girl in school, while the popular students in the real world are the nobodies.
