However, she is aware of Sylvia's tragic fate—an execution at the hands of the merciless Crown Prince Oscar—and that's the one thing she absolutely refuses to sign up for! Yet, somehow, the Oscar in this alternate world begins to show interest in Sylvia... Could there be glimmer of hope for a better conclusion for her?
