Jesus, you guys are so hung up on tags. There is the typical Japanese style NTR stories that follow the usual structure of NTR progression. Then there is the western stuff that are cuckoldy (usually more about male protag humiliation than female corruption).
Then there are the stories that don't follow strict genre conventions. This is one of those. Tags should just be a guideline for the players to get an idea because you never know how weighty the tag is or even if the tag is correctly used by your standards.
To me, this isn't an NTR story at all, and that's been pretty evident for a while. The writer never really delves into the NTR tropes. There is rape, blackmail, sexual misconduct, misunderstanding, betrayal, and other unsavory elements in the story, but there was never a corruption arc for the mom or GF. Plus, the characters are entirely grounded in reality (except Parker's braindead moment regarding Becky's pic lol). That's almost antithetical to NTR which relies quite a bit on tropes.
Maybe this is the NTR that some people have been asking for. One where the MC turns things around lol. Maybe it's not NTR at all. Whatever you want to call it, just appreciate the damn story as the dev intended.
so I'm hoping the 'A' endings have enough fireworks to end the novel with a bang.
