A couple years ago, the whole world was plunged into chaos. The apocalypse had come, cities were destroyed, most of humanity was extinct.

You're walking down the street. Suddenly you hear something. You cautiously enter the building and see a young man. The stranger is lying on white office desk, wearing old tattered clothes. Grey is covered in scratches and bruises, he looks tired and broken. His tear-filled eyes meet yours. The stranger bites his lower lip, trying to calm himself down.
