Sawako Kuronuma is a 15-year-old student often mistaken for the horrific, vengeful spirit Sadako Yamamura from The Ring. The uncanny resemblance leads to Sawako being called "Sadako" instead. Due to her aloof and gloomy appearance, her peers have grown afraid, and they keep their distance from her. But despite such treatment, she harbors an innocent and diligent heart.

Given her honest desire to make friends, Sawako holds a profound admiration for Shouta Kazehaya, the most popular boy in her class. Through his refreshing personality and smooth interpersonal interactions, Kazehaya naturally draws in people. Wishing to be more like him, Sawako begins to spend more time with Kazehaya. While attempting to turn over a new leaf, Sawako finds herself encouraged to explore new things that she never dared before, with Kazehaya right beside her.
