NTR stands for Netorare. In manhwa, it usually involves a situation where a character's romantic partner is stolen or seduced by someone else, causing emotional distress for the character.
Power struggle is also seen. The character seeking revenge may be in a position of weakness at first, but through their journey, they strive to gain power over those who wronged them. They might use different means, from outsmarting their enemies to physically overpowering them, all in the name of getting back at them for the injustice done.
One example could be 'Jane Eyre'. In this novel, there are elements that can be related to a form of 'revenge' in the sense that Jane, after facing hardships and mistreatment, stands up for herself and finds her own path and happiness, which is a kind of victory over those who wronged her in a way.
I don't know exactly who said it. It could have been a protagonist who came to this realization after going through a series of challenges and learning lessons about the futility of revenge.
One reason it stands out is the detailed world-building and the unexpected turns in the plot. Also, the character development is really well done, making you root for the protagonist throughout the story.
Well, 'ntr fiction' typically refers to stories that revolve around the concept of 'netorare' in Japanese. It can involve love triangles or situations where one character's relationship with another is interfered with in unexpected and often emotionally charged ways. It might show how characters deal with jealousy, betrayal, or unexpected changes in their romantic relationships. It's a rather niche genre in the world of fiction.
