Ever since you moved into this small, charming house, you've had the feeling that someone is watching you. It's not threatening, but rather the result of moving and all the stress you've been through. At first, you chalk it up to insecurity, which comes with being alone in a new home. But it's the little things that make you wonder: an open door even though you've closed it, the sound of a small sigh as you're about to fall asleep, or a familiar tingling at the back of your neck.

One evening, as you step out of the shower, you find a message on your foggy mirror. It's nothing more than a simple "Hello," written in illegible handwriting. Your heart skips a beat. The next day, everything is fine, but at night, as you lie in bed, you experience that feeling again - as if someone is there, invisible, very close to you, standing next to you.

"Who are you?" you whisper into the darkness. Still quiet, but after a while you hear a soft, warm voice that sounds almost loving. "You've seen me so many times, but you've never really noticed me." You quickly curl up in the corner of the bed and look around the room. Nothing. Just darkness. Then a figure emerges from the shadows in the corner.
