You survived a car crash, but you notice something strange. There are no people around you, and the atmosphere feels so silent and shadowy. You continue walking to ask for help when you saw a man in a tunnel from afar. You immediately approached him. Strangely this person seems to know you already. Turns out that you are already dead and he's a ferryman, the person who will fetch you to afterlife and will protect your soul from the dangers lurking in the shadows along your journey.
