Yes it's pretty much a starter pack now. Cold duke of the North, Sea lover Duke of the South, Knightley Duke of the West & Sickly Duke of the East. All have fixed personality for some reason. And we are being trained to accept these stereotype
LOL, that's why now we can see more manhwa that also sarcastically talk about this issue. I don't remember which one it is, but a few days ago I read a manhwa where the MC reincarnated in a noble lady's body and need to go to the North to send a marriage proposal, by the time she arrive there, she can guessed that the Northen Duke have black hair, emotionless, war hero, etc. I bet the other authors also feel tired to see their "compotitor" writing that way lol
Does every romance manhwa author use the same blueprint for their story? Like Grand Duke of the north, black hair, emotionless, war hero, and has a bad reputation yet is a softy.
