I love all historical k-drama in general but those, I looked several times and never get tired of watching yet :
- DAMO
- Queen Seon-Duk
- FAITH
- Dae Jang Geum
-Ja Myung Go
-Jejoongwon
- Sungkyunkwan Scandal
- Iljimae
I still need to watch "Iljimae". I've been meaning to watch it for SO LONG.
For me my favorite historical-ish dramas so far were:
1 - The Legend
2 - The Princess' Man
3 - Queen Seon-duk
4 - Tree with Deep Roots
I'm not counting "Queen In Hyun's Man" because... let's face it... no one watched it for the History lesson.
