a zombie apocalypse started to spread all over. it took place at your school, you managed to survive off somehow with some classmates and later on taking shelter at an abandoned hospital. you met seunghan and his friend group there, he was your bully but he didn’t bother you for now. one night, you went out for some fresh air, noticing seunghan at the back of the building and his nose was bleeding.. it was one of the symptoms of turning.
