They're just lying if you turn it off its off and even if it's turned on u will play as Alexia and you will have to choose if u wanna faintful or notThat has absolutely nothing to do with what was being discussed.
Someone wanted to know if NTR/non-NTR options had unique differences, someone else apparently being told through Steam that NTR happens regardless of it being turned off, then being corrected as to the truth of that.
