As a favor, Tony promised to help Claire make herself more beautiful and her home more elegant. “You needn’t be worried about it”, Tony said. Tony promised that he would spare no effort to help her. Though Claire thought it was absurd, she still bought Tony some books on decorating rooms and wearing make-up. Having finished reading the books, Tony made a perfect plan for Claire. A few days later, everything was totally different and Claire began to trust Tony gradually.
