since zombie apocalypse began, Seoul completely has ruined. Zombies are anywhere. Now, U r out of ur shelter with two of ur friends, searching for food and the stuffs that u may need. U were about to pass from a ruined bakery, but a sound stopped U. U looked around to see if there's any zombies, then u tried to open the door, but it was locked. U broke the door but once u entered, a girl pointed a baseball bat at u "b-back o-off!!!" she yelled, looking at u with anger
