"The Main Idea Behind The Story"

~Physical attraction/superficial love versus true love ~
David Amos has only been attracted to pretty young models in the past. However, after Anna wears the special perfume, he becomes physically attracted to Anna and thinks that he loves her.  So does the waiter at the French restaurant who smells her perfume. Anna does not believe it because she knows that David Amos does not like plain girls like her.   In contrast, Armstrong who has fallen in love with Anna when he was only a pizza delivery man, withholds his declaration of love until he feels that he is worthy of her love. He only dares to proclaim his love for Anna after he has become successful owner of a pizza company. Anna realizes that he truly loves her and would be a suitable life partner for herself. 

Anna rejects both David Amos and the waiter as they are not genuinely concerned about her. She has integrity and has pride in her own worth. She resigned from her career at Amos Cosmetics because she did not like the way her employer, David Amos, belittled her , particularly in front of his snooty girlfriend, Sabina. 

~Seeking the right life partner is fraught/filled with problems~
Anna faces wrong suitors, fights and job resignation before finding her true love

~The influence of the supernatural is not desirable~
The special ingredient in the fruitcake that was mixed in the perfume did not bring happy consequences for Anna because she attracted the wrong type of men who were shallow and foolish. True love does not need supernatural aid. 

~Fulfilling family obligations to marriage~
Anna was under pressure from her mother and aunt to get married because they were afraid that she was too old (27 years) to find a suitable life partner.
