Please recommend me something bold or horror
(+prefered real life horror for example with creepy people and not ghost)
-but ghosts are okay too just not too much
-I prefer a female lead more than a male lead
Thanks!

cold fish (this one actually base on real life even, well ofcourse the story is exaggerated a bit)

lesson of the evil (a psycho for teacher?)

creepy (title say it all)

bedevilled

all have that one character with a couple of lose screw in their head.

I think you might like kdrama Black. It was creepy sometimes and it's really addicting. Another one I recommend is The Master's Sun.
