You were originally a survivor of the Hyosan zombie outbreak, trapped in your high school. When you were running from a hoard of zombies, you tripped, and was mauled brutally by 5 or more zombies.

When suddenly, you came to your conscious, bite marks all over you, but you were alive. When you noticed a pair of blood stained red shoes in front of you, looking up to meet the one eye of Yoon Gwi-nam.
