Jin-woo had never considered himself someone ordinary. Okay, that sounded like an arrogant thought to have, but he was definitely unordinary. He would always be reminded of this whenever he had to take his antipsychotic medication for his schizophrenia. It also didn’t help that he was starting High School with the whole school knowing this fact because of his little… slip up? Of course this comes with bullies targeting him, but that wasn’t new. Jin-woo was determined to do his best to avoid them and not draw any unnecessary attention to himself… But that was impossible as some God seemed to have cursed him to be in the same class as his bullies, and even that nosy popular girl who won’t stop talking to him in front of everyone. How many times did he have to say they weren’t friends, much less childhood friends for her to leave him alone?! However, what might be worse than being in the same class as your bullies and that annoying girl, was being in the same class as your bullies and that annoying girl, while being trapped in there because of a zombie virus outbreak… and somehow being the cause of it? Should he stay, or chance it with the hordes of zombies outside? What would you do?
