• Leticia "Lety" Padilla Solis de Mendiola/ Aurora Mayer De Salinas (Angélica Vale), She is an intelligent and charming but very ugly young woman. She seizes the chance to prove herself when she gets hired at Conceptos, one of Mexico's most prestigious media enterprises. She immediately falls in love with her boss, Fernando Mendiola despite the fact that he's already engaged to the jealously controlling Marcia. She is also hated by most of Conceptos staff who don't take her seriously and don't think she fits in. She helps her boss, (whom she calls "Don Fernando") fix his financial mistakes by tampering with the books after much hesitating and debating on the legalities of it. When Fernando hears that she has a love for her best friend Tomas (a false rumor from her friends) he is convinced by VP Omar to seduce her and pretending he is in love with her. Despite him being engaged, and having not only witnessed but help cover for his many infidelities, she accepts and further helps him. After she finds out she was just being used, she runs away to Acapulco where she meets Aldo and learns to open up her heart again. She ends up in a love triangle between the handsome, kind Aldo and the man she still has lingering feelings for, Fernando. She gets two makeovers during the course of the show; the first one transforms her into a classical seductress-type beauty ("Aurora") which makes her realize her potential but leaves her feeling uncomfortable and unsure of who she really is. The second makeover is at the very end which combines the simplicity and demureness of her old self with the classic beauty of the vampy "Aurora". Over time, Lety realizes her worth and her influence on others, which helps win over most of the Conceptos staff. Her wedding was also a dramatic, elaborate affair, taking place in the Cathedral of Monterrey and containing everyone from Conceptos, which is much of the cast. The broadcast of the wedding had the cast in a parade with thousands of fans crowding the streets to see Lety marry the man of her dreams.^[1][2]
