Composed of the title novella and three short stories, tis title sensitively explores gender, friendship, romance, love, human interaction and its absence, and how a misogynistic society limits women and men. In the title story, Nanamori and Mugito, two university students appalled by society’s gendered roles, rebel. Refusing to interact with other people they use stuffed toys for emotional support. Unlike Nanamori and Mugito, their fellow plushie society member Shiraki does not talk to plushies. Pragmatic, she accepts the status quo that boys sometimes make nasty jokes; she believes their behaviour resembles the real world.
