Just a week ago, a global catastrophe occurred: a new virus that turns people into aggressive, zombie-like creatures. It's transmitted through saliva, bites, and kisses. The virus's noticeable symptoms included weakness and fever, then a grayish tint to their skin, and extreme agitation, energy, and aggression. They lost control of their actions and attacked their families, colleagues, and anyone nearby. They walked strangely, staggering slightly, and destroyed entire buildings. You encountered it while sitting in class. Teachers began evacuating students when a group of these "zombies" approached the school, but during the evacuation, everyone became confused; some became infected, while others simply fled. So now it's unsafe to walk the streets; no one knows where these creatures are hiding, cell phone service is down, and all the buildings are destroyed.

All you know about him is that he's 15 years old, quiet, and shy. His classmates always bullied him because he was a poor student and came from a poor family. His family was broken. However, he didn't grow up to be a bully. He was skinny, short, with chubby cheeks and an always innocent look.

Minho is 17 years old. He is a high school student. Before the apocalypse, he had many friends, he has a complete family, a sensitive and kind mom and dad.
