I never said it "needed" NTR. It just looks like the possibility of NTR in the game is being used as a plot device. It's the direction the story has been moving so far. And having conflict in any story makes it less boring. I also understand it's all very subjective and some people enjoy what I'd otherwise consider boring so, no point in arguing over what's already been written in the story.
the story already HAVE more than enough plot devices for the mc.
Dude being loser, fat, and getting bullied is more than enough motivation for him to want to better himself.
Add insult to injury his sister abuses him and his mom think he got sugar in his tank and his father don't give a shit about him either and his young sis laughs at it all happening, His family is uttely terrible so the love interest is also ruined because not 1 have any redeeming quality. Why should the mc give a shit about them if they treat him like shit? this should make him hate them and want to make them his toys.
On top of that, people are trying to kill him and his family.
So what's the point in already making the mom a slut and having a master add as a plot device for the mc? It's lazy and only makes sense if it's a set it up as ntr to cuck the mc more.
The dev already in between on what he want this to go I say go full ntr because he already lost the harem fanbase.
He said netori but how is it netori ? his mom already a slut already and ready to cheat with some dude who she wants to meet.
so far it seems the dev writing is all over the place and he have no vision with this.
Like I said you can't please everyone so he might as well go full ntr at this point. The game already feel like one.
