Sawako Kuronuma hat es schwer, sich einzufügen. Manche sagen, es liege an ihrem pechschwarzen Haar, andere sagen, es liege an ihrer gedämpften Sprechweise, und wieder andere behaupten, es liege an der Ähnlichkeit ihres Namens mit Sadako, einer Figur aus einer beliebten japanischen Horrorserie. An ihrem ersten Tag an der Highschool trifft Sawako den einzigen Jungen, der sie wie ein normales Mädchen behandelt – Shota Kazehaya.

Known for her semblance to the Sadako character of The Ring series, Sawako Kuronuma is given the nickname "Sadako" and misunderstood to be frightening and malicious like her fictional counterpart, despite having a timid and sweet nature.

From their first meeting, Sawako has admired Kazehaya's ability to be the center of attention and aspires to be like him.

When Kazehaya organizes a test of courage for the entire class and encourages her to attend, Sawako sees this as an opportunity to get along with her classmates, starting with Ayane Yano and Chizuru Yoshida. Through each new encounter and emotion she experiences, Sawako believes that meeting Kazehaya has changed her for the better. Little does Sawako know, her presence has also changed Kazehaya.
