After reading one part of the  story, the reader is the pro protagonist, I get a lot of from it. One of the messages is that in some cases, what you see is not true, and you shouldn't believe it. In the story, I know that the woman 's ex-husband told her that his life was an open book before dating. However, after they married, something had changed. The wife realized that her husband killed a man for a girl. Also, her husband being  sarcastic said that never judge a book by its cover. The woman thought he was a monster while the husband thought  he was a hero. Absolutely, it just from how people judge in their ways. Most of times, there is no denying that people are  more likely to know others by their appearances. From this way, I think it is not respectful to others, and we should stop this.
