Leave it to the fucking Japanese...
It's okay, I'm sure there's worse shit out there. At least you don't fap to guro or some shit. Right?
Okay, first of all, what the actual fuck is "netorase?" You're joking right? There's no fucking way there's a third NTR term. That's just obscenely unnecessary. Secondly, I feel like NTR has become so vague that some people take it to mean just instilling jealousy in the MC because he sees someone he would like to fuck being fucked. I understand if you're not into cuckolding, but without the relationship aspect, it's pretty much just voyeurism, which is fairly vanilla if you ask me. Anyways, point being, I feel like people make way too big a deal out of NTR being in these games because it's usually just a handful of short scenes, not the entire plot revolving around you getting shafted.
Not sure wtf a "yandere" is, but if it just means homicidal psycho bitch, then yeah, that pretty much describes my ex to a tee.
I'm an only child too, but I enjoy it. However, whenever my brain starts to wander unbidden towards people I'm actually related too, I'm like "wow, thanks brain, totally killed the mood there, jackass."
