Sasaki, an overworked salaryman, finds a release of his daily tensions in the customer service of Yamada, a winsome, cheery supermarket cashier. One day he finds himself working late, and, finding Yamada already done with work for the day, goes for a smoke, he finds a mysterious woman, "Tayama", who invites him to the smoking area behind the store.
Jinushi was serializing Rokurei - Tenseishi Rinne Kuyakusho Dairokkanbu Joreika Katsudouki in Monthly Big Gangan. He received advice from his editor to draw a short manga as an exercise in creative writing, which led him to creating the series. Since Rokurei which was being serialized, was a supernatural story, the manga was drawn to be more realistic, and since the author had a background in customer service sales, the story was set in a supermarket.
When the first chapter was posted on Twitter, the tweet received more than 190,000 likes (as of June 2, 2022), creating a huge response. As of June 25, 2022, the total number of likes for the series had surpassed 2.5 million.
On August 25, 2022, the serialization in the magazine began in Monthly Big Gangan. In this issue, it appeared on the cover and in the opening color. On the same day, the first volume of the book with newly written chapters was also released.
