Shirley

Kaoru Mori's "Shirley" is an evocative glimpse into the daily life of winsome, 13-year-old Shirley, a maid in turn-of-the-century England. It's been compared to Yokahama Kaidashi Kikou, as both mangas feature languid pacing, atmospheric backgrounds, and a female main character who works in a cafe.
No hentai, no fanservice, zero, zip, nada. Just pure maid-tastic moemoe.
