I felt like there was much joy in how Keiko had found her place in life, and fulfillment through doing a good job at the convenience store. Nicely critical of the way the people around her -- her so-called friends -- can't accept the choices she's made that make her happy and keep trying to push her into something else. The only sour note for me was Shiraha; I get why he's in the story, but every page with him on it was so unpleasant (perhaps I'd become weirdly protective of Keiko?) that I enjoyed the last third of the book much less than the preceding two-thirds.
