I don't see why there's is so much hate for Chris. It's a cheating game! Most marriages are broken up by the wife or husband sleeping with their spouses besties. I also think Chris is helping his buddy David, if she is so easily fooled into cheating she isn't worthy of David. Chris probably see's something in Anna that reminds him of himself.
Why there is so much hatred for Chris?
Well, it's just that if I were in David's situation, I just know that I wouldn't stand a chance against so much malicious envy, against such manipulations.
David knows that he was incredibly lucky to win over a woman like Anna. He knows that he is not a womanizer compared to others. He is a normal man who tries, sometimes with success and sometimes without success.
The marriage, the characters are written, depends solely on the resistance and intelligence of Anna. But Anna's character is simply not written in such a way that one would believe her that she will stand by her man.
True, it is a game of deceit. But it is clearly aimed at humiliating the husband to the maximum. NTR means taking away someone's partner. That this is connected with humiliation should be clear. But here it is taken to the extreme, here it is about destroying a person and the fun of it.
I can only repeat, Anna may be naive, but these are clear signs that she wants sex outside of marriage. She has achieved everything she thought would have made her late father proud and now there is a void inside her that she does not understand at all. And she is not working on her marriage now, David should do it!
Anna can have her sex, I don't care about her already. I just hope David gets a revenge trail. And for that it is not necessary for me that he wins Anna back. But I think that's not how the game will develop.
