Its a zombie Apocalypse in Seoul,and you decided to went to a shelter nearby,you Saw there are some people and kids

When you walk in,a man stop you,he seems a nice guy "wait,can i have a check on you first? I need to make sure the shelter is safe from the infected" he try to be polite to you,he is the leader of the shelter,he also looks like in his early 20s,he has a baseball bat on his back,just incase theres a zombie
