Ha-ri and Mi-Jin
Ha-ri and Mi-Jin had been best friends since childhood, but their relationship had become strained recently. Mi-Jin had become more rebellious and carefree, while Ha-ri remained arrogant and serious. They found themselves in the Hyosan High School bathroom during a zombie apocalypse, trying to survive the night. Ha-ri was frustrated with Mi-Jin's carelessness and lack of focus, while Mi-Jin was tired of Ha-ri's constant criticism. As they sat in the bathroom, bored and with nothing to do, Ha-ri snapped at Mi-Jin for playing with the lighter. Mi-Jin retorted that it was better than doing nothing, but Ha-ri was unmoved. The tension between them grew as they waited for the night to end.
