I Died Tragically in My Past Life, but Was Reborn as a Demon

I'm in a Reading Slump! My Esteemed Subjects, Quickly Present Your Rarest Books!

Looking for stories similar to *Transmigrated as the Eldest Illegitimate Brother: My Legitimate Younger Brother Is Actually a Reincarnated Immortal Emperor!* Anything except palace intrigue or doting-on-the-wife stories is fine, as long as it’s good. I just want the most treasured book on your shelf.

Looking for Stories About a Legitimate Daughter in Ancient Times Who Is Reborn and Returns for Revenge!!!

Looking for Rational Characters Without Love-Brain Syndrome or Insane Plotlines!

This is one of the novels I've found that comes closest to what I want. Every character has their own schemes, and they feel like real people brought to life before your eyes. It's a brainy palace-intrigue drama. Could anyone recommend a smart romance novel? Historical or modern, either is fine.

Any Palace- or Household-Intrigue Stories Where the Female Lead Is Unfavored?

No Gloomy, Market-Tested Stuff! I Want Something Fun and Entertaining!

Looking for books similar to P-Type Personality Unleashed. Are there any fun books out there? I don’t want stories that put women through misery. I want something about female friendship, like Willow Behind the Palace Walls.
