NTR is the most generic story in erotica at this point it is vanilla.
NTR will become oversaturated in the next 10 years imo. It will lose popularity, it has passed its peak during 2019-2022 (Terasu MC, Ratatata, Laliberte, Dramus and etc). It’s like the Battle Royale of any East Asian Erotic Works. Everyone is jumping on it because it makes money and brings food on the table. But eventually people will become desensitised to it. Losing its major selling point which is the shock factor it brings. In comparison to a genre like Romance which caters to the human instinct of wanting affection and to be loved, hence why the Romance genre can never die. NTR feels like a phase, the only thing carrying the genre is the art it produces. At some point, artists will also move onto the next big genre.
There is one trope NTR fans/artists refuse to explore and that is NTR Revenge/Karmaic Justice where it’s bull/cheater getting cucked for a change from the perspective of the bull/cheater, it’s a hidden gold mine. But otherwise, the hypno trope, the blackmail trope (Idol caught by paparazzi with MC, FMC was AV actor/prostitute in the past, FMC was caught doing something illegal, FMC caught masturbating by bull, and etc), the debt trap trope, the bully trope, the drugging/drunk mistake trope, the emotional vulnerable trope, bro. I’ve seen it all with NTR. It’s repetitive and tiring.
