Traces of an Ambiguous Past

I’m Out of Books to Read, Please Recommend Some

Looking for books similar to *Your Highness the Regent, Your Assassin Is a Few Cards Short of a Deck!* Transmigration, reborn, historical romance, contemporary romance, post-apocalyptic, quick transmigration, or any other genre is fine, as long as it's good. No tragic stories, and it must be complete. No mindless plots or saintly protagonists who meddle in everything.
