A shy college student, Kakeru Sorano, meets a woman at a university welcome party. Her name is Fuyutsuki Koharu. She has a well-refined appearance and smiles softly, but to Kakeru, she seems as if she lives in a different world. She says cheerfully, “I'm blind. That was the beginning of everything." Even though she is blind, Koharu acts as if she is fine and is positive and cheerful in everything she does. When I began to notice the difference between the world she sees as a blind person and the world that she sees as a person who can see, I began to want to make her dream come true together with her, “Someday I want to do fireworks with my friends.” Because it is invisible to the eye, this is a special love just for the two of them.
