Dramas with a sweet and kind FL

I'm looking for dramas with a sweet and kind FL who is possibly also innocent and shy. I don't mind if she's a damsel in distress or a doormat, I'm just looking for something different after watching so many dramas with strong FL's. I prefer historical dramas but I'll also consider modern ones as well. 

Shows I've already seen and have what I'm looking for:

• JIN 
• The Long Ballad (SFL)
• Love Between Fairy and Devil
• Mars
