This is not true. According to the genre, NTR is understood as "when LIs being taken from MC by another character", in other words - MC being a cuck. If we have sex with someone who was seen in sexual interactions and this is not a full-fledged LI - this is not NTR. I mean, you meet a girl, have sex with her, and realize she's not a virgin. That doesn't make you a cuck. That would be an absurd worldview. But there is a problem - dozens of fragiles that scream NTR!!! and break threads. Not a problem for DPC. And he slightly tests the waters in Ep. 10 - we had Jacob who tried to kiss Zoey, Jacob saw Sage naked, gradually develops the topic with Elena - he watches how his audience reacts. For some it is enough to start raging. But DPC doesn't give a fuck about the Zone, and he can always ban those who are crying on Patreon. After all, it's happened before - the J/M reveal in Ep.3 led to a shitshorm in the thread from the anti-NTR mob, actual fires, and the active ones I know avoiding the thread and the game. And it's always been a militant minority, not the majority of the audience.
Further I propose not to develop this topic. Mods do not like NTR discussions. I have expressed my position on this matter.
