Ugh, I don't dislike NTR, hell sometimes I actually like it when it's really well done. But I really hate when it's used on character archetypes that are quite literally the complete opposite to its purpose.
Like really? You're gonna make NTR of a Yandere, a character that's so obsessed with another character that they would willingly murder other people? Including the object of their affection? But here they are screwing someone other than their target? Suspension of disbelief and such.
