Every person is a weight, Rai-kun. Some are heavy like stones... and some are feathers. But when someone leaves, they leave a hole. And a hole has its own weight." Seventeen-year-old Rai Takahiro is a master of invisibility. To him, the world is a monochrome landscape of gray atoms and cold logic, captured only through the lens of his Nikon camera.

Vibrant, popular, and inexplicably drawn to the boy in the shadows, Hikari breaks the silence of Rai’s rooftop sanctuary. She speaks of "holes" in the world and the "weight" of existence, hiding a flickering terror behind a blinding smile. As the monochrome boy and the translucent girl bridge the gap between their worlds, Rai begins to realize that some moments can''''t be captured in pixels—and that the most beautiful colors are often the ones that hurt the most.
