The story tells the story of Kazuki, the male protagonist who immigrated to Japan with his parents. In his father's hospital, he met Shion, who has been hospitalized for many years due to physical disabilities. When they first met, Shion read a novel called "Dandelion Girl" to Kazuki. The following story did not end plainly, but was actually closely related to the content of "Dandelion Girl" and involved the past of Shiyin's parents. . .
