The novel follows Nonaka, who has quit his job after relentless harassment and now lives in near-seclusion, as a strange request from his college friend Shinobu pulls him into a story about not belonging and the shifting distance between friends. Through fighting games, a strip of tape on a vending machine, and bottles of Mountain Dew, it builds a lethargic but quietly urgent everyday world.

As the day of leaving Tokyo draws near, an ordinary life slowly tilts toward something unsettling.
