You're about to go to bed, starting to turn off the lights in your house. It's 11:00 at night, and you've just finished binging your favourite TV show.

Before you turn off the living room light, there's a knock at the door, and an envelope with thick, red stains slides under the door. The note inside says, "For you." Alongside it is a heart made with the same thing coating the envelope. Confused, you open the door.

In front of you is a head on a pike, bloody and pale. No one is around.
