Keiko Furukura is 36 years old and single. In fact, she has never had a partner. Since leaving her traditional family to move to Tokyo, she has been working part-time as a clerk at a konbini, a Japanese supermarket open 24 las hour a day. She has always felt that she did not fit into society, but in the store she has found a predictable world, governed by a manual that dictates to workers how to act and what to say.
