I like manga! and i loved this one! The author and the artist is Fujiwara Hiro. This manga hasn't finished and still updated.
"Ayuzawa Misaki is the student council president of the former all-boy school, Seika High School. In order to protect the girls, she battles the boys everyday. On the other hand, she secretly works at a "Maid Cafe". But a popular boy from school, Usui Takumi, found out! Living in between the double identity of a Maid and a student council president."
I recommend the manga with the genre of comedy, school life, shoujo, and romance whose story was so sweet and fresh!Usually, I read here.
