As a child, Natsuki doesn’t fit into her family. Her parents favor her sister, and her best friend is a plush toy hedgehog named Piyyut who has explained to her that he has come from the planet Popinpobopia on a special quest to help her save the Earth.

On an unnamed island off an unnamed coast, objects are disappearing: first hats, then ribbons, birds, roses - until things become much more serious. Most of the island's inhabitants are oblivious to these changes, while those few imbued with the power to recall the lost objects live in fear of the draconian Memory Police, who are committed to ensuring that what has disappeared remains forgotten. When a young woman who is struggling to maintain her career as a novelist discovers that her editor is in danger from the Memory Police, she concocts a plan to hide him beneath her floorboards.

Mikage is an orphan raised by her grandmother, who has passed away. Grieving, Mikage is taken in by her friend, Yoichi, and his mother (who is really his cross-dressing father), Eriko. As the three of them form an improvised family that soon weathers its own tragic losses, Yoshimoto spins a lovely, evocative tale with the kitchen and the comforts of home at its heart.

Yoshimoto spins the stories of three young women bewitched into a spiritual sleep. One, mourning for a lost lover, finds herself sleepwalking at night. Another, who has embarked on a relationship with a man whose wife is in a coma, finds herself suddenly unable to stay awake. A third finds her sleep haunted by a woman against whom she was once pitted in a love triangle.

Young is a cynical yet fun-loving Korean student who pinballs from home to class to the beds of recent Tinder matches. He and Jaehee, his female best friend and roommate, frequent nearby bars where they push away their anxieties about their love lives, families, and money with rounds of soju and ice-cold Marlboro Reds that they keep in their freezer. Yet over time, even Jaehee leaves Young to settle down, leaving him alone to care for his ailing mother and to find companionship in his relationships with a series of men.
