Shiawase Kissa Sanchoume

Shiawase Kissa Sanchoume (otherwise known as Happy Cafe) is a 15-volume manga series by Kou Matsuzuki.

Sixteen-year-old Uru Takamura is constantly mistaken for a child due to her short height and is uncannily strong. After her mother got remarried, Uru decides to live by herself so she won't burden them. Hearing how happy the customers of the Cafe Bonheur are, Uru resolves to get a job there. Among her co-workers are twenty-year-old Satsuki Shindou and eighteen-year-old Ichirou Nishikawa--the former a yakuza-looking guy on the surface who really has a kind heart and the latter a Bishounen who ends up falling asleep whenever he's hungry and can only wake up when fed food.
