>What happened that it became this way?
Japan happened. Japanese women are cheating sluts who will give their pussy to any man who is handsome or rich enough while their cuck husbands work 12 hours a day for an average salary. They are even easier when they are not engaged and just have a boyfriend. It's a cultural thing; all these characters and scenarios don't come from the minds of people who just have an NTR fetish, they are simply transferring what they see in real life to fiction.
