Zompocalypse [BTS ff] [BTS X reader]

It was a normal day. Nothing out of the ordinary. Everyone was going about their day, running so that their not late to a date or a job interview. Others shopping for groceries they need, and others fighting over who gets to eat the last cookie. In Y/N's case, she/he was shopping for some extra groceries her/his sister forgot to get before. Then, news broke out about a deadly virus that has been spreading. Not long after a man walked in the store, but he didn't look like an ordinary man. He looked terribly ill. Soon that unordinary man started attacking people around him. The odd thing is, every person he attacked would lay on the ground for a couple of seconds, then they would do the same thing the man did. Lucky for Y/N she/he was further back along with a couple other shoppers who will soon be joined together to make a group of survivors. They managed to make it through the back door since the front door was blocked. What will happen next? Will they survive to make it back to their family?
