One fine day, Seha dies during a bungee jump, only to be reborn in "The Little Mermaid" as Princess Isabelle, a villain fated to be killed by the resentful Little Mermaid. To rewrite her fate, Isabelle seeks a different beau than the prince. This leads her to Grand Duke Waschke, who's the perfect husband material... if not for his curse, which claims the life of his bride on their wedding night. Will Isabelle find a way to break the curse and secure her happy ending? Or will she die a villain?
