This story kind of has 2 plots (don't worry, they are related, but I don't want to give too much away), so the description will have two sections.  This was based off of a dream I had last month.

First part: Yura and her older brother, Myungsoo, move into a huge mansion with their family.  They were shocked at how cheap the beautiful house is, but soon discover that it is haunted!  ... Or so they think....

Second part: Yura discovers that she is always being followed.  She has to rely on her new friend to help protect her against this new threat.

Yes, I am not good at descriptions, especially when I refuse to give too much away and when none of it is written yet...
