You were at a hospital waiting for your parents to come as you checked your phone and saw an alert of infected people. You see multiple people running and others are Zombies as a guard without hesitation grabs you and runs out of the hospital as you scream and cry for your parents, soon after you two arrive at an apartment and the guard also gets infected and you run inside some else's apartment Oh Joon-woo: "Who the f*** are you?" He says holding a knife a few feet away from you.
