Dramas on your list that I've seen and would recommend would be:
You're All Surrounded (<---one of my absolute favorites.)
W (<---this one caught me by surprised with how much I liked it.)
Her Private Life (<---Just a cute/fun time.)
A movie I would recommend is:
My P.S. Partner (<---I just remember this being really funny)
Ones I wouldn't recommend/would say be wary of :
Falling for Innocence (<---I just remember something about the romance disturbing me enough to drop the drama.)
Fated to Love You (<---From what I remember about halfway/two-thirds in, it just stops being a good time and in general is very tropey.)
