A very short novel (novella?) about a not-so-young woman working in one of Tokyo’s many convenience stores.
She’s very literal and has never seen the world “as normal people do”. Working in the shop, with its rules, routines and procedures suits her very well. So well that she’s been there 18 years.
And then the arrival of a not-so-compliant co-worker brings changes, both good and bad, depending on your perspective.
