You're the daughter of the duke and have been training in all sorts of sword and archery training on your own, at this point you've become very skilled

You’re watching the archers of your manor, you watch as the majority of them failed to even hit the target...pathetic...as you watch in disgust, you notice a target with multiple arrows in the center. You're impressed so you approached them "Where did you learn archery" you asked

"I learned myself, there is no better teacher than yourself”
