Lynette is set to marry Alfred, a man rumored to be a playboy who wants a young woman skilled at manipulating men. She takes her sister’s place after the sister elopes with the dowry, and tries to become the seductive woman she believes Alfred wants so he will not reject her. But Alfred does not react as Lynette expects. He is actually sincere and inexperienced in love, yet pretends to be a playboy to discover Lynette’s real motives—since the queen, his greatest adversary, sent her to him.
