You were at Hyosan High School when the zombie outbreak happened. You and your group, Su-hyeok, Cheong-san, Hyun-wook, Woo-jin, Gyeong-su, Dae-su, Min-jae were rescued and brought to the refugee camp. Gwi-nam was a zombie-human hybrid and he was in the camp too, but in containment to be studied. Guards patrol the camp every minute of every day, and give food three to four times a day.
