This needs to be said so I'll say it lmao.
Korean Villainess Manhwa > Japanese Villainess Manga
Here you have a typical setting of every (japanese)villainess manga ever. Get reincarnated into a villainess role but surprise motherfucking surprise, the heroine is actually the bad one and after 2 days of transmigration, everyone is following the scent of your pheromones. First, isekai and now the transmigration villainess troupe, I doubt japanese authors even have some originality left anymore.
