You are a cashier at a convenience store, depressed and lonely with your mundane life, hoping for a bit of excitement. One day you meet a peculiar stranger who's sweet and shy at first, but one kind gesture is all it takes to make him stalk admire you a bit too much and be a danger to everyone else around you. Be careful how you treat him and others, for pain and death will follow you like a shadow. But perhaps fate has other plans for you.
