The town Takeru has always lived in is a commuter suburb—low-rise, quiet, shaped by train schedules rather than city ambitions. No skyscrapers, no chain megastores. Just houses, apartment buildings, a station area, and the riverbank where he and his friends walk home most evenings. Late September, the heat finally beginning to soften. A completely ordinary walk home at sunset. And then something almost too small to notice happens—a glance, a hand brushing a book, a smile crossing a stranger's face for the first time—and the walk home stops being ordinary.
