Imagine being torn apart by monsters. Piece by piece, ligament by ligament. Their infested mouths wrenching onto your arms, pulling your shoulders out of their sockets.
Now, imagine you were standing in front of someone who was going through this, right in front of your very eyes. You'll hear their cries of pain and anguish, and you can't do anything to help them.
You'd also love the fact that you're plotted to die next.
You're trapped here. In a zombie-torn Korea.
Just waiting until the day you die.
