There are a few that more or less match this setting. The further down, the less it matches ;)

i srs thought u were talking abt I Became The Wife of the Male Leas- but then u said it all happened in the first ch lol
.. Idk why I didn't add that to my list.. And it's not like it was really good.. But I just suddenly had this urge to find this
It's not this one.. Sorry
here's a list of "northern duke" trope, maybe it's one of those?

Thank you!!
Umm.. There's this manhwa I've been searching for.. I don't remember much.. But there's the fl with maybe white or pink hair and she goes to the region where the ml is(I don't remember she was sent there by her family or willingly went) it's a cold place with snow and all.. Also the ml is very suspicious of the fl due to some reasons.. And I'm not sure but maybe she cured ml's brother or close subordinate.. All this happened in the 1st ch.. And then I didn't read anymore.. Does anyone know this manhwa?
