Imouto wa Namaiki Kasshoku Maid-san.

"She’s supposed to be a healing maid, but behind the scenes, she’s got quite the attitude!"

A single flower blooming in a struggling (?) café.
A maid with a sunny smile, a warm demeanor, and a tan line that catches the eye.
But her true nature… is that of a cheeky, bratty girl.
