Unwilling to give up, she struggles to regain control of her life, but one sentence from him throws her into disarray: “I love you!” Only in the end does she realize that his confession was just another ploy to manipulate her. She no longer believes in love and tries to return to her own era, but has no idea how to find her way back in this vast world. Thanks to his schemes, she finally understands that no matter how skilled a doctor she is, she cannot cure the world's most painful illness: a wounded heart!
