Junko had been creating "yaoi" manga professionally since her debut in 2009, and after reading some of her works, a staff member from "Bessatsu Friend" invited her to contribute to the magazine. Junko decided to focus on an "otome" game concept, and after the editors had asked her to make the series comedic, Eiki Eiki suggested making jokes about "fujoshi" culture. Junko created Shima when she wanted to add a new male character to Kae's group and later decided to make her female.
