Why do people hate NTR so much they abandon the idea of objective voting? Oddly enough, this is the case for most English sites. Vanilla guys follow the NTR tag just to berate every new title they found. They remind me of SJW in their crusade against the NTR.
Meanwhile, this manga looks promising to me. That's how you do NTR right, give the reader a better male (or even a woman) to relate to instead of cuck.
