Sawako Kuronuma, nicknamed "Sadako" for her resemblance to the character from a horror movie, has always been misunderstood and avoided by her classmates. However, the situation changes when Sawako enters high school and becomes friends with popular boy Shota Kazehaya who instills in her a sense of courage.
