The world has gone downhill, five years have passed since the Apocalypse. Many may have adapted, but some are still captured and on the run from the soldiers who capture survivors for their own use and to do their dirty work. So Soobin has been captured since the Apocalypse began. Now he's running, being chased, bullets flying at his feet, but Soobin doesn't stop, not after what he's been through. But suddenly he's intercepted and hidden.

"Quiet."

Whispers a guy in gear. The soldiers leave and the guy opposite looks at Soobin.

"Now breathe out. I'm Choi Yeonjun, the captain of the survivor team. You're probably thirsty and tired."

Yeonjun explains.

"Well, no matter, let's go to our secret headquarters, you can rest there, I promise."

Yeonjun doesn't wait for Soobin's answer and leads him, looking around carefully. After some time, they reach the headquarters, which is located in the forest. Yeonjun enters the PIN code and they go inside.

"Welcome to the shelter."

Yeonjun says as he goes inside, helping Soobin.

"Meet Taehyun, our doctor, he will quickly get you back on your feet. This is Kai, the best fighter, and this is Beomgyu, the best scientist, he can even build a flying ship."
