スイッチガール!!

Nika Tamiya is the most popular girl at her high school when she is in "on" mode: made up, dressed to the last detail, friendly with everyone. At home in "off" mode she lives in a ratty sweatsuit and glasses, hair tied back over games and manga, and she guards that secret closely. Everything shifts when transfer student Arata Kamiyama moves into her building, catches her off guard, and turns out to run on the same on/off switch, hiding a handsome face behind his own scruffy mode.
