A secret feline “matchmaking network” quietly pairs lonely humans with the right cat at the right moment — five interlinked short stories that turn everyday urban loneliness into gentle, redemptive connection.

NNN stands for Neko Neko Network, a legend that circulates among Japanese cat lovers online: a secret organization that overhears when someone wishes for a cat, judges whether they would make a good owner, and quietly sends one their way. Arimi Yazaki turns the legend into a novel told largely from the cats’ side. In every neighborhood, the strays know one another, trade gossip about the humans who feed them, and decide who deserves a cat and which cat deserves them.

Each story finds someone quietly running low: a single man of thirty-three, alone since his mother’s death; a schoolboy worn down by cram school and empty evenings, chosen by a kitten with a crooked lucky tail; an elderly widow who believes she is too old to love another animal; a college student whose missing stray leads her into a grieving household; a woman who has wanted a cat for forty years, and a husband with his own reasons for saying no. Each is nudged—never pushed—toward a cat, and through the cat toward other people.

The guiding spirit is Mike-san, a calico who watches from sunny balconies and garden walls, vetting each person’s character before a cat is sent their way. The book slips between human and feline points of view: the humans hear only meows, while readers hear every word the cats say, and see each situation more clearly than the people at its center.

Warm, wry, and quietly moving, it is a novel about how loneliness eases—not through grand gestures, but through a small warm creature arriving at just the right moment.
