Usumudang Gadooshim

This is one good short series that you can watch in a whiff without giving intricate thinking about the plot and the drama involved. I won't say that this is the pinnacle of kdrama, but it's good one definitely worth a watch, especially if you like ghost stories in Korean dramas (which are normally good).

So here is the plot, Ga doo shim is born into a family of shamans, although she doesn't like to be the one she does some little helping for her mother. One day she transfers to a school where kids who gets the lowest rank dies mysteriously. She teams up with the top student Woo soo to unravel the mystery and save her fellow mates.
