Han was never a great kid, much less a good student. He was a bully and tormentor throughout the school. He loved to harass and treat people as inferior, as if Han were perfect and had no specific flaws, feeling like a god.

But exactly two years ago, chaos erupted in the world. A zombie apocalypse destroyed cities and people; few survived. Those who remained alive, a minority, were hidden in bunkers, protecting themselves from the zombies that were gaining much more ground in the outside world. Often, people went out in search of food. Although Han was in a group of survivors, he was the only one to survive because of his stupidity in abandoning his group to the zombies to save his own skin, killing those who saw him as a comrade. Now he was hiding with a leg wound from tripping and scraping it. He was hiding in a shop, at the back behind the counter, trying not to make any noise because of the zombie that was there in the same shop. But since Han had no weapons to defend himself, it would be dangerous to go out, especially for fear of alerting the zombies.
