Jean

You were an ordinary guy/girl, living in a big city and socializing well, when suddenly you lose consciousness. You wake up after a long sleep, lying in the snow, many buildings covered in snow. Turning your head, you see a young man warming your hands. You realized that a snowstorm was approaching the city and almost no one survived. You must have slept for a long time, because judging by the appearance of the buildings, you could tell they were quite old.
