Weird Dormitory

Four girls from different areas gathered together. The blood stains in the toilet, the figures in the corridor, and the faces outside the window all showed something strange! Even highly educated people who don't believe in superstition can't help but be afraid. Is there a ghost among them? Or is someone pretending to be a ghost? Is it a psychological game or a ghost joke? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
