From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): This 4-koma style manga covers the daily life in a little coffee shop. This little coffee shop has a little, child-like boss, 30-year-old Tsukishima Aya. She's extremely fast at her job, though, and very precise in her work. 25-year-old Senkawa Tomoko is the waitress, a larger woman than little Aya, who complements Aya's personality. [tethysdust]
