It is NTR. It's just netori not netorare since it's the MC stealing other people's lovers not the other way around. They unfortunately use the same acronym for netorare, netori and netorase despite them being pretty different as far as content goes.
That is true. I'm just saying that the original japanese title has NTR on it and they probably revised the title because its too long when translated to english and the NTR part might stop some people from buying the game.
