Plot.
Nika Tamiya, the most popular girl at her high school, is a "switch girl" — in public, she is in her "on" mode, where she is as a put-together, charismatic, and fashionable girl. However, in private, she is in her "off" mode, where she is unorganized, unfeminine, and lazy. One day, Arata Kamiyama transfers into her class and moves into her apartment building. Not only does Arata discover Nika's secret, but he also has an "on" and "off" mode, where his "off" mode reveals he is secretly handsome. As Nika urges Arata to keep her "off" mode a secret, the two begin to learn more about each other and fall in love.
