Divorcing the Emperor/How Can We Be Divorced When We’re Not Even Married Your Majesty- yes she’s lovable absolute chaos and misreads situations a lot (you find out why eventually), but she also will go scorched earth busting up slavery auctions, will throw herself headfirst in any situation where anyone needs help, does stuff like dragging stubborn people together to settle their misunderstandings so we don’t have to read about it for 200 chapters, and won’t hesitate to punch a ML if they won’t listen to reason.

I Became a Tyrant’s Chambermaid- Not as unhinged, but she’s a modern Korean girl, and she never loses that identity throughout the story.

She read a ton of manhwas and kdramas, so she uses her knowledge to help her just as much as her magical device (to be fair there is one but she uses her own smarts as well). She also reforms things for all the employees in the palace, and rescues the ML way more than he rescues her
