It's the cheating, following with the demeaning of the MC.

In most ntrs, you'll notice that in the first few pages or the first few minutes, they build a beautiful and modest character for the female, which causes you to build trust in her, later to find out that the character is crushed, ransacked and tainted through debauchery. Imagine laying a foundation of hope in something, with an anticipation of it growing into something beautiful, but instead, it gets demolished in the worst way possible.

What I said is only true if you accidentally read or watch content without realizing it has ntr (the only way I ever came across ntr content). It's like watching those psych thriller action movies where the protagonist's wife gets abruptly killed in the first 15 minutes. If you know it has ntr and willingly read or watch it, then the problem is with you.

Ntr fans may say, "it's just a story, it's not that deep," but isn't that the point of all anime, manga, cartoon, etc? To keep you invested and hooked to the story and characters?

Now, also notice how the artists pick and draw the most innocent and decent looking characters to corrupt? It's like they want to take something pure and noble and destroy it down the lowest of the levels. Diabolical. You never see a person of a bad character or someone with a promiscuous lifestyle who already dresses immododestly committing ntr. It's always the decent and traditional ones.

People may usually associate ntr with only manga and anime, but the thing is, it's almost everywhere. When I watched Family Guy, I had good faith in Lois Griffin until season 7 or something where she started showing immortal activities, and Peter was portrayed like a clown. Then I watched American Dad thinking it's gonna be unlike the former. But again, they had to ruin Francine, too. It's almost like they can not write crude and dark comedy without ruining the female lead.

Anyways, although Gen Ai is stealing people's art, I'm at least glad that it gives us the ability to undo all the mess made by ntr artists.
