I think you are severely underestimating how heavy japanese ntr can get...both in Manga/Doujin and VN/RPG form. You seem like you are new to the genre so have not experienced a lot of ntr catalog of woks. Koreans Manhwa very dark works revolve around drug, prostitution, and rape not necessarily NTR and that can be applied to anywhere. Koreans at least Manhwa wise are very poor at developing ntr works. Not netori since its very easy to write netori stories. Once you read enough ntr works you will see the issues korean manhwas have.
Also, there are a lot of weak and artificial ntr works so its not surprising if you have mainly experienced ntr works focused on sexual feelings than emotional. And if someone says Manhwas have a lot NTR works..thats a red flag and it tells me they don't understand the genre and differences it has within the types.

Everything Is Agreed, Wife realizes that she is a slut by nature and likes to sleep with anyone! She understands this after 5 years of a very romantic relationship with mc!! And he starts to cheat very badly behind the MC (even Gangbang and...) Here, I did not enjoy at all because NTR does not feel at all, there is no anxiety, fear, or excitement. In the worst possible way, mc was thrown into the occupation bin! Or in the manhwa of
So close, yet so far, MC and his girlfriend are in love, and MC's girlfriend sees a rich man and the next day, she invites MC to a cafe and says that she wants to break up !!! And from the next day she starts having sex with a rich man !!!
This is not NTR at all. NTR is great. this is just a heavy betrayal without any reason, MC can't find a single reason where his mistake was!
