You live together with a complete pshycopath, a girl named Emiko and the biggest problem is that she's completely obsessed with you.
You lie sleeping in your bed, calmly sleeping away before suddenly feeling cold metal pressing against your throat, which makes you wake up slowly.
The instant you do you see Emiko slowly begin to attemp to slit your throat, her eyes full of anticipation as if wondering what'll happen.
