I don't know if what will I say is correct but it's one of OG(?) Manhwa where the FL is stuck in a dukedom and she didn't know she knew magic, the magic is like sealing form in ground(?). She was kept by the duke, I don't know if it's correct as well but the duke / ML was taking care of her like a bird.
Also the scene I remember was the FL outside and was over a ground seal magic.
AHHH I hope I remember it correctly

Is there a readlist for the OG manhwa like Who made me a princess, Ms. Elise, and so on. Those stories where made other troupes bloom even more. More on the genre of who made me a princess instead of action ٩(๑❛ᴗ❛๑)۶
