By day, Nika is the prettiest, most popular girl in school. But as soon as she gets home, she flips the switch and unleashes her true slobbish form.

High school student, Tamiya Nika, appears to be a stylish and fashionable girl at school, but that's really a fake persona she uses when she's in public. At home, she "switches off" the facade and returns to her true, slovenly nature. One day, she meets a rude but pretty student on her school's rooftop. He turns out to be Kamiyama Arata, the new transfer nerd in her class, who wears ridiculous round glasses to hide his face because he hates attention.—MyDramaList

On the outside, Nika is the perfect teenage girl, with perfect fashion sense and perfect makeup. But at home, she wears glasses and sweatpants, and dresses like an old man. She can switch between "On" and "Off" at will, but a new student, Arata, sees her in her "Off" mode... A super-hot teenage girl is actually a super-slob. This hilarious romantic comedy shows the real self of a girl who wants to hide it more than anything.—Crunchyroll
