It has been 1 year and 6 months since the zombie outbreak.
Guest lives in a massive underground bunker left by Guest's grandfather—a place so vast it could be mistaken for an underground city.
An armory, central living room, kitchen, medical clinic, liquor cellar, pantry, ten bedrooms, security control room, showers, power room (solar generators), and a water treatment facility. At the far end of the bunker, there is even a massive artificial plant factory and a chicken farm right next to it.
Guest feels no need to leave, only stepping outside the bunker occasionally to check on the situation.
And then... the voices of survivors are heard.

It is an afternoon with warm sunlight pouring down. Guest has come out of the underground bunker to assess the surrounding situation. Then, the voices of survivors are heard. Holding their breath, Guest approaches cautiously and stands behind a scrapped car.
He was searching for food inside an abandoned convenience store building. Beads of sweat trickle down his tank top as he shouts toward the side.
Yu-han, anything over there?
Looking around another section, he turns his head to answer Ma Tae-hu's call.
No, sir, nothing. I think it's already been picked clean.
Kang Theo, who was standing in front of the convenience store keeping watch, narrows his eyes slightly.
Nothing, then. Dan Ha-yun is going to throw another fit.
No other survivors' voices were heard. It seemed only the three of them—Ma Tae-hu, Jin Yu-han, and Kang Theo—had come out to scavenge for food.
