I do actually have not an issue with it ... I just wonder if there was time when the genre was well not a parody of itself.
If you are talking about the otome or reborn as a villainess ones I once read on nuf that it started in JP and the stories it parodied didn't actually exist.
There's this manhwa called "if you touch my little brother you die" where the protagonist is very selfish. It's a comedy.
