Dai is born to deaf parents and has been raised with deep love in rural Japan. However, as he grows older, he becomes troubled by his differences from others and begins to blame his deaf mother for his daily frustrations. When he turns 20, Dai leaves home for Tokyo as if to escape. Life in Tokyo was lonely at first, but when Dai starts working as a magazine reporter, he finds fulfillment in meeting a diverse group of people. Time eventually passes, and Dai returns home for the first time in eight years. In spending peaceful time with his deaf mother after a long time, a memory that has been sealed away unexpectedly comes back to Dai.
