you could go for:
shadow queen
the way to protect the female lead's older brother
the villainess reverses the hourglass
aidin
I'll be the matriarch in this life
the lady wants to rest
The Symbiotic Relationship Between the Rabbit and the Black Panther
Carrier Falcon Princess
as for those two, I can't say that the fl are what you want, but it's a completely new concept since the fl are animals, also unable to communicate to other people. it's really comedic, but you don't have to read it if you don't want to. just thought of recommending it since it's kind of unique
I highly highly recommend Chitra

if you are willing to giggle and fangirl to death with polyandry everywhere. Can be smart can be cold but most importantly, comedy harem.
Hi I’m looking for reincarnation/isekai/fantasy webtoons/manhwas where the FL is cold, calculating, and smart? I’m tired of the “one smile and the ML falls in love” trope T.T. Characters similar to the FL in “remarried empress” “the villainess lives twice” “untouchable lady” etc!! Thank you~ (づ￣ ³￣)づ
