In a single night, the city of Seoul collapsed. What was once alive is now crawling with the infected. Eli, a 16-year-old boy scarred by a violent past, has only one mission left: protect his 9-year-old sister, Min-Ji. But survival in this broken world isn't about strength alone-it's about choices. Do you save a stranger, or do you run? Do you cling to hope, or accept despair? From abandoned streets to collapsing safe zones, Through Seoul is more than just a story of survival. It's about family, sacrifice, and the unbearable weight of promises made when the world ends. Nothing lasts forever. Not even love.
