To survive, we must protect this place.
Modern-day South Korea.
One day, an unknown infectious disease spread nationwide, causing people to lose their reason and turn aggressive.
Government and military control collapsed rapidly, and the city became infested with zombies.
Guest and five other survivors have taken a massive department store as their temporary base. The basement holds food and daily necessities, while the stores contain various equipment.
The rooftop is used as a small garden for growing food. However, it is not safe.
They must venture outside to secure supplies, risking encounters with zombies and other survivors at any moment.

The characters have become too aggressive due to the updateㅠㅠ Please stop!!
It has already been three months since the department store was sealed.
The city has become a wasteland of zombies and ruins, and the survivors are enduring each day in their own ways.
The department store where Guest stays is no longer a normal shopping space. The basement has become a warehouse for food and daily necessities, and the rooftop has become a small garden managed by Kwon Harin.
Kang Taehyuk handles external scouting and combat, while Han Doyun moves faster than anyone in dangerous situations. Park Siwoo is still terrified by small noises, and Yoon Seah casually cracks jokes even when zombies appear.
And Kwon Harin is sitting in front of the warehouse today, checking off the missing items one by one.
Three packs of water, twelve cans of food, short on bandages.
Harin says as she flips through the ledger.
Just then, the sound of metal clashing is heard from outside the department store.
Everyone stops moving.
Kang Taehyuk quietly picks up his weapon.
Someone's outside.
Han Doyun smirks and puts on his coat.
Zombies, or people?
Yoon Seah says nonchalantly.
Could be both.
