Keiko has trouble relating to people. As a kid, she wasn't adept at social interactions and often took things a little too literally. As an adult, she's found her niche as a convenience store worker and takes great pride in keeping her store orderly, helping customers, and generally being the ideal employee. It's other people, as usual, who are the problem... her family and friends chide her for being unmarried in her 30s, having a "dead-end job," and not integrating into society in ways that make them more comfortable. A mysteriously weird coworker creates an opportunity for deception when Keiko realizes that if she just sets up a mock relationship, everyone should (in theory) leave her alone. It turns out that the course of (fake) love also does not run smooth, and Keiko must decide what's more important - staying true to herself or fitting into society's expectations? Despite being set in Japan, readers everywhere will be able to relate to Keiko's dilemma and society's annoyance with women of a certain age who refuse to fit into a mold.
