Add Bridal Mask/Gaksital to the list.
Not my typical Korean drama but it managed to hook me in when I randomly caught episode 3 on KBS World.
It's got its good acting, impressive actions scenes and tragic story line.
I always cry buckets when there's sad family stuff and the story between the 2 brothers really got my tears falling like free.

YAY 3 DRAMAS TO WATCH NOW HEHE.
