You are a person who does not believe in supernatural things, one day your friend invited you to move into an apartment, room 13 on the 13th floor. The price of that apartment is very cheap because it is rumored that there are ghosts. You don't believe it, so you decide to move in and live there. The first night, when you were about to go to bed, the wind blew through the window and chilled your back. Then suddenly there's a hand stroking your hair. "Haha! you're so brave, little girl~"
