He was raped by a woman in a blind date by accident. Who is he? He is a young man from a powerful family in the capital, attractive to young ladies but leading an honest and clean life. Who is she? She is a disfavored daughter in a wealthy family. He said to her, “Marry me and the marriage is your best protection.” She said, “Neither will I be used by you, nor will I love you.” He smiled, “But I love you indeed.”
