Also, I'd pick-up Queen In Hyun's Man from your on-hold list back up again. It was hard for me to initially get gripped on the story too, but it definitely improved and I was glad I watched it.
38 Task Force -- if you want something original
All In !
Bad Guys !!!
Cinderella and the Four Knights -- if you want something cheesy but fun
High School - Love On
Missing You
Vampire Detective !
A Girl & Three Sweethearts!
@KSuuh Age of Youth and Another Miss Oh are two of my absolute FAVORITE dramas of all time. They are so worth the watch and quite unique on their own respects.
