But what i learned to enjoy in those kinds of story( that being the reason why i still read a lot of NTR doujin, in hopes of finding something similar), is that the kink has an expiration date. So, when it comes, it makes you wonder if the payoff this time will be satisfaying.
So, like I wrote in my post, josei cheating stories but for men.
In josei, when the man cheats you know that by the end, he will be ruined, the mistress will be ruined and the FMC will have an happy end with a better partner in every way.
It's really puzzling for me the absence of the same trope in seinen. I think that the first author who publish a decent work where the betrayed man comes out on top and the cheaters get their comeuppance will make bank, at least in the West.
