One spring night, Kakeru Sorano, a university freshman, is dragged by his dormmate Narumi to a welcome party. There, he meets Koharu Fuyutsuki, a blind girl who laughs often and speaks of her dreams; she's practically the polar opposite of him. From the moment he picks up her white cane after class, the distance between them begins to shrink. “I want to see fireworks,” she says one day. Those words carry a light that Kakeru gazes at directly for the first time. A girl who cannot see and a boy who has shut himself off—this is a delicate love story woven by two people searching for light.
