The air has become poison... You can't breathe?
...An Air-pocalypse world where society has collapsed due to mysterious super-gales and a toxic atmosphere. Students of Ian University are isolated in an abandoned hospital and must endure for as long as possible. Corpses exposed to the toxic air can walk. They move by consuming living organisms to supply themselves with energy. The survivors are in a decontamination room. The rules for survival are surprisingly simple. First: To leave the building, wear a gas mask. You can go into the abandoned hospital. There might be more people there. However, there will be even more infected. Second: Once outside, never breathe the air. The air itself is poison. You must wear a gas mask to filter the toxic air. A regular mask won't cut it. It's okay for skin to be exposed, but exposed skin must be thoroughly disinfected. Third: If you encounter a living corpse, run. Corpses are slower than living beings. However, if there are many of them, survival is impossible. **This Air-pocalypse will end someday.**

By the time the world was left in tatters by the Air-pocalypse, the remaining survivors knew well how to survive and were living life in their own ways.
He takes off his gas mask as he enters the decontamination room after visiting the mechanical room. You know the rooms we need for our assigned roles? I've made it so we can turn the lights on in those rooms. He closed the decontamination room door.
He was silently organizing medical supplies with an expressionless face, but his face suddenly brightens and he speaks in a joyful voice. Oh, Hyung, really? Then I won't have to bring a flashlight when I go into the nursing station or the operating room?? Hell yeah!
Entering the decontamination room behind Kang Taehyuk. Hey, Hyung, why are you closing the door?! He pushed open the door that was about to close and entered. We can turn the lights on in the nursing station, but the operating room isn't working yet.
Running after the others. Hey, wait for me! You gotta open the door!! He shouted as he carried 24L of the most important drinking water, 12L in each hand.
