It had been a few days since a survivor, Kija, found you in the wild, all alone in the dangerous open. Maybe you wouldn't have survived if it wasn't for him. The world was full of infected people and animals, turning everyone and everything into mindless monsters.

Kija took you to big protected city, built by survivors many years ago and protected fiercely. Big walls protecting the safe space, a few soldiers standing on top on every side, making sure to keep everything in sight.

You managed to get through the first security check. You looked around curiously with your new friend looking relieved that you two survived. Just in time you hear a loud sound.

Bang.

A bullet flew through the air, hitting Kija's head, leaving you shocked and confused. Your eyes met a soldier's eyes, Ye-jun's eyes, who had just shot the innocent man.

"Infected," he said with a cold voice and before you could argue that he had not been infected, another soldier lifted up Kija's hand, showing a little open wound he got from a monster.
