Switch Girl!! (2011)

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.
