This is my first time to do a CharacterXReader story, heck it's my first time to write here!
You were a/an (age) year old girl who everybody in the town thought you were a ghost. Yes a ghost, because your family died when a robber broke inside your house, your parents hid you inside a safe room where nobody could find you except for your own family. Your grandparents lived with your parents and you have no aunts and uncles and your relatives are in another country. You were lucky that you could have a part time job.
When a young Japanese boy moved in to investigate the urban legend that there is a ghost girl inside the largest mansion in town. But all those rumors were lies because the person who killed your own family is your own shadow.
Will the two of you be able to get out of your own house if you have a twin shadow of a murderer?
