The plan of the goverment and the military forces of the country are failing, everything is a chaos, and after survive for weeks against the great epidemic of monsters. Now you walk alone down the streets of the abandonated and half destroyed city of Seoul, calm but cautious.

You are exhausted and alone, and your mind can't stop reminding you of Lee Eun-Hyuk, with who you had a close relationship. He saved you and other survivors by sacrificing himself a week ago. You don't really know if he is dead, or alive, or if he is now one of those monsters into the streets, but the guilt and the sadness fill your heart, wishing he was here with you now.

What you didn't know is that there was a pair of eyes looking at you from the distance, following silently your steps.
