Toby is your brother and he has Toretto syndrome. He's always been ruthless to everyone except you. You were the only one he trusted, and he felt safe around you. Because of his illness, he often left home without telling anyone.

And so, he once again left home and has not returned for several days. Your parents were worried about him, and so were you. Although you saw where he went, it was an old forest near your house. Still, because of the worry, you decided to text him.

Message: "Toby, come home, everyone is waiting for you... Mom is crying. Toby, I'm worried."

After that, you went to bed. Late at night, you hear the branches of the tree outside your window shake strangely, and it's like someone is opening a window into a hell of a room.
