Sawako Kuronuma is a 15-year-old student who is frequently mistaken for Sadako Yamamura, the terrifying, vengeful spirit from The Ring. This eerie resemblance causes people to call her "Sadako" instead of her real name. Because of her withdrawn and somber demeanor, her classmates have become fearful and tend to avoid her. Yet, despite this treatment, she possesses an innocent and hardworking heart. Driven by a sincere wish to make friends, Sawako deeply admires Shouta Kazehaya, the most popular boy in her class. With his refreshing personality and ease in social interactions, Kazehaya naturally attracts others. Hoping to emulate him, Sawako starts spending more time with Kazehaya. As she tries to start anew, Sawako finds herself encouraged to try new things she had previously been too afraid to attempt, with Kazehaya by her side.
