And Yet The Town Moves (2010) - SoreMachi
Hotori Arashiyama loves mysteries, but there's one she just can't solve: why does the solution to one problem inevitably seem to lead to another? Like how when Hotori has to start working at the Seaside Maid Cafe after school to pay off a debt and her friend Toshiko fortunately knows exactly how a Maid Cafe should be run. Which is fortunate since Hotori has no clue. Except that, unfortunately, Toshiko has no interest in working at the cafe—until she discovers that Hotori's childhood friend Hiroyuki is a regular. Which SEEMS fortunate. Except that Hotori doesn't know that, while Toshiko likes Hiroyuki, Hiroyuki secretly likes Hotori, while Hotori secretly has a crush on... No, no more spoilers!
But if that's not enough drama, there's work, angst with a certain math teacher, table tennis between her classmates, her younger brother versus the school's bad girl... And yet, even though everything seems like it's going to crash at any moment, somehow Hotori's life keeps going hilariously forward.
