Rose was the campus belle who frequently mocked and bullied her overweight classmate Lilith. During a club activity, the two unexpectedly swapped souls. Lilith, who had long endured bullying, became twisted inside. After taking over Rose's body, she turned licentious. Rose's attempts to dissuade her proved futile, and Rose eventually conceived murderous intent. Just as she was about to act, she was mistaken for Lilith and bullied by her former friends, leading to her accidental death. Upon learning of Rose's demise, Lilith was deeply shaken and resolved to live life on her own terms.
