A 2005 shōjo manga series written by Fujiwara Hiro and published by Hakusensha's LaLa magazine, later turned into a 2010 anime series by J.C. Staff.
Ayuzawa Misaki lives a double life. At school she's the strict, man-hating first female Student Council President of Seika High School, a former all-boys school still notorious for its rowdy males, resulting in very few female students. After school, however, she works as a maid at the Cafe Latte. One day, however, her secret is discovered by impassive and popular Usui Takumi. Fortunately for her, Takumi decides to keep her career a secret from the rest of the school, and has been visiting the Cafe ever since, with Misaki oblivious to Usui's growing affections for her.
