We’ve all had that nightmare where we’re late for a test, right? How about the one where your teacher’s trying to kill you?! Just me, huh? Guess it’s only fair then that I woke up in an actual zombie-infested nightmare! Almost everyone on my campus has become a creepy, flesh-eating monster! Except for this one ax-wielding badass named Youngwon Ki. He seems perfectly fine with all the chaos. I’m glad he’s here, but I don’t get why he acts like we’re close!
