This doujin is to NTR what NTR is to happy sex, haha. Obviously pretty self-aware, given the conventions of the genre. It's like it's tweaking the beaks of people who actually like NTR by teasing that kind of ending, then swerving at the last minute and going in another direction.

Kind of an interesting concept, not gonna lie. Feels unique because I haven't seen a setup quite like this before.
