Trying to find this Manhwa

I remember reading it briefly on Mangago.com, it was about a girl who lives out in the woods but is a princess or a bastard princess. She's uneducated but know how to fight with a bow and arrow? If I remember that correctly, also I think her entire family was assassinated and the soldiers are trying to find her so she can take over the empire or kingdom, since she's the last remaining heir. Supposedly the handsome male lead comes to look for her, and she misunderstands thinking he's going to attack her and the forest she dwells in. But he says he's not here to fight but here to ask for her hand in marriage. She agrees immediately, and the ML is surprised, but then the FL asks what even is marriage. Then they realize, she's never been educated about anything and that's why she doesn't know what marriage is. I think she had red hair on the cover art or in the actual manhwa.

I know this might be a tall order, but any leads would be helpful. Thank you in advance!
