Finished

어느날 갑자기 서울은

Yeon-U is on a school trip to Seoul, excited by the chance to get closer to his crush, So-Yeon. However, a mysterious and terrifying virus suddenly sweeps through the city. The virus manifests as mutant cells that transform anyone who touches them into hideous, flesh-hungry monsters.

Trapped in the heart of the outbreak, Yeon-U and his classmates' dream trip turns into a desperate fight for survival. They must navigate the collapsing city, avoiding the infected and the multiplying cells, as they search for a way to escape Seoul before it is completely consumed.
