Extramarital affairs have ever been described vividly in literary masterpieces in which the authors exposed the reality at the time authentically. On the other hand, these passionate writers were in full sympathy with their heroines. These women's immorality seemed to be justified in the name of seeking the freedom of individuality. If so, people involved in affairs would be encouraged to degenerate further. These works can only be appreciated but not taken the guide of our life. We should draw a lesson from the tragic ends of the loose women. Never marry such sort of sirens who would destroy our life.
