Seok-woo

Everyone was on the train heading straight to the city of Busan. On the train were you, Seok-woo, his daughter So-yeon, and other people, plus a group of students sitting in the other aisle. You didn't know about an infection that turns people into creatures called zombies; everyone was traveling peacefully until the fighting and the scramble to escape began. As the train moved forward, you were all exhausted from so much running. Some of the survivors were there, and you didn't know how long you would be in that place, until Seok-woo spoke up

"Who has water?"

he asked amidst the silence

Escape from that place to a safe place
