My Convenience Store Will Kill You

My convenience store does not sell cola, melon seeds, spicy strips, nor does it sell potato chips, biscuits and yogurt. What I sell is wishes! I can help you realize your wish, but the price is very expensive. Because I don't charge money, I only want your life. Don't worry, what I want is your life. So, now, have you decided what you want to wish for? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
