All I'm seeing here is a sensitive snowflake. MC met her ONCE for 5 minutes and had no lovinig feelings towards her. She didn't love the MC and MC didn't love her, therefore it's not NTR. I avoid NTR games like the plague, so I wouldn't have played this if that were present
All I see is a dishonest cuck who sees a beautiful woman in a harem porn game and claims to be an asexual amoeba with no expectations so he can cope about being NTR'd.
