Everything’s Fine

Emily feels a lot more tired than usual. Ethan knows something's wrong, but his sister insists that everything's fine. She says he can't go to the attic. She says that it's empty, and there's nothing interesting up there, but he knows he didn't imagine the fear in her eyes she gazed upon that locked door. Emily's acting strange. He often hears her talking to herself in the bathroom at night, repeating over and over, that "everything's fine". Isn't it?
