I love it when a female travels in time in ancient Japan, Korea or China. It doesn't matter which country it's from, then she meets the royal family from that time. I know there are plenty in K-dramas, I've seen almost every one that I could find on google. The ones I've seen :
1. Scarlet Heart
2. Jade Palace Lock Heart
3. Moon Lovers : Scarlet heart Ryeo
4. Naughty Princess
5. Go Princess Go
6. The Eternal Love
7. Faith
8. My only love Song
9. Splash Splash Love
I can't wait for Aishi girl and Rule the World to finish airing so I could binge them. So far, Aishi girl's I love. A note : it has to be a female lead that captures the heart of a few princes or high ranking nobles. Just can't get enough of them! I don't like them when they're traveling from the present to the future, or from the past to the present or future.
