The confused mix of disdain and desire towards the fmc is similar to an incel's mentality.
Unlike for Felix the events of this story are part of a kink for the reader to enjoy. Requiring that Sophie gets remorselessly punished for doing things that turn you on is a bit of a self-own.
Yea, no.
This is only true if you pretend the kink is exclusively limited to seeing the MC get blown the fuck out (ie. the Western Cuckold fetish). But it isn't.
The Japanese 'Netorare' genre is filled with stories that either imply or flat out tell you that the guy the FMC has fallen in love with is just using her for sex and that he will dump her as soon as he gets bored with her. In those stories, the FMC's degraded, fallen state is just as much a part of the kink as the process of her getting stolen from the MC.
Of course, it's not always the case, but it's so normal that you really shouldn't be surprised if the FMC ends up alone and miserable at the end of everything. After all, it's a normal part of the kink.
So, if you can say that wanting to see Sophie get used up and thrown away in this kink is a 'self-own' and makes someone 'similar to an incel', then I could say that wanting to see her get a happy ending in this kink is a 'self-own' and makes you 'similar to simp.'
Then again, maybe we could all be adults and recognize that people come to netorare for different reasons without resorting to name calling?
...No?
Fine, whatever.
I debated whether to reply but decided why not? Incel ending? Where the husband who did nothing wrong gets destroyed and left by his wife? Don't think so. the incel ending would be Sophie deciding that she would rather be with her safe husband than the alpha male. The only person who gets a happy ending is Zack so how is that an incel ending? Please explain.
And you should have chosen not to. Learn to recognize bait, friend. Hopefully what I typed above makes things clearer for you.
