I havent read it but I've heard good things

Is there a transmigtation story from past to future word? And the historical knowledge/norm is their cheat. I hope not chinese manhua though, I'm not used to their fast paced story. Manga or manwha recomendation please

Both of these don't fit your desc, just are similar to parts of your desc
'Roujoteki Shoujo Hinata-chan'-- this ones like an incarnation, slice of life-ish story where the mc uses their old age knowledge for daily activities.
'Rewriting the villainess' -- doesn't quite fit the description either but this one does have the transmigration plot from historical to the modern world, although their past knowledge is not really much in use, it's just more of a plot about them helping the character of the modern world.

I want to read romance fantasy manhwa. But lately most of my encounter is with either the fl is completely dumb/naive and only good or the fl is so strong/smart everything is easily solved with a little contemplating and.
I want the fl in between. A little naive but smart in the obvious things. Any recommendation?
Still searching for teacher theme manhwa ,little to no romance, if any not harem please. i've read A Villain’s Will to Survive, Academy’s Undercover Professor, One hit teacher master baek, Lightning degree, Sensei!
