I actually don't remember but what i know is that about apocalypse/zombie. The MC go to the amusement park eventho he know that it will soon be apocalypse. Then when it happen, he try to save someone that get stuck i think and pull the person to the rooftop but he got caught by the zombie. He transform to zombie but not actual zombie bcause he does not eat human flesh and have brain to think not like others zombie. I think his lover or what that searching for him and when he found that he become zombie, he still try to save him.
