On-jo is the daughter of a firefighter and a rescue captain, raised on survival skills that suddenly become a matter of life and death. Sweet-natured but tougher than she looks, she anchors the central group of survivors with her steady nerve and her quiet, long-running crush on her best friend Cheong-san.
As the outbreak escalates, On-jo's practical knowledge, learned from her dad, repeatedly saves the group, from improvising weapons to navigating the school's hidden corners. She refuses to abandon anyone, even when staying together puts her own life on the line, and that loyalty defines her every choice.
By the finale, On-jo has endured staggering loss and emerged hardened by grief but not broken. Her journey from ordinary teenager to reluctant leader is the emotional spine of the series, and her resilience carries the survivors toward an uncertain dawn.
