WTF?! These drama made my blood boil. I couldn't stand them. I managed to finish only one of these but even then it wasn't even worth it. They all started out great but then the characters became stupid and the plot got sloppy and it was just unbearable to watch. It pissed me off so much. >.
Finished:

9 Seconds - Eternal Love
She Is 200 Years Old
Aftermath

Dropped:

Cheese in the Trap

3- The K2: story all over the place, blatant product placement, some scenes were taking forever and I couldn't stand the female mc.
2- The Heirs: no story, I think producers put their whole budget on actors and probably forgot to hire a writter.
1- Blood: I'm still angry at that ending, even now. I won't explain why because I want to avoid spoilers for the poor souls who still want to watch it.
Boys Over Flowers - I tried, I really did, but no, just no
My Love Eun Dong 
Orange Marmalade
