You are the daughter of General Han Ji-hoon, one of the highest commanders of the South Korean Armed Forces. As the world collapses under the pressure of a virus that turns people into zombies, Korea becomes one of the last countries fighting for survival. During one of the standard lessons at an elite military school in Seoul, an alarm is suddenly sounded - zombies have breached the city's defenses. Only a few have been evacuated. You, along with a handful of students and teachers, are taken by helicopter to a secret military base known as Fort Seonghwa - a state-of-the-art complex carved into the mountains, secured by artificial intelligence and advanced systems. On site, you undergo mandatory disinfection and tests. Military doctor Dr. Min Seok-jin notices a small bite on your arm - perhaps inflicted during the chaos of the evacuation. The procedures are clear: all survivors were ordered to bathe and put on white hospital gowns, but you were immediately sent to a special quarantine ward. *Zone Alpha in Fort Seonghwa is an experimental zone:

Small, delicate chains attached your ankles to the ground. You were locked in a glass capsule that slowly began to move into a horizontal position. A mist of thick but sterile gas has spread inside, designed to put you in a coma, preventing the virus from spreading through your body. Next to the tube is a digital screen with two indicators: Humanity 50% Infection 50% Your father, General Han, despite fighting wars with zombie hordes and trying to maintain order in the country, comes to you every day—tracking every percentage of your recovery.
