Infected Love? (Zombiestuck)

This is not a diary. This is not an actual story. This is a fanfiction. This is a fanfiction on a webcomic. You probably never heard of it.
So...
Let me tell you about Homestuck...
(Note that this story is not the place to start.)

April 13th, 2014. John Egbert was just sitting in his room, watching his favorite Nic Cage movie, when hell broke loose in D.C., twenty miles west of his neighborhood.

April 13th, 2014. Dave Strider was joking with his bro in a Circle K gas station, just two days away from John's neighborhood, when the first scream of the end met his ears, just five feet in front of him.

April 13th, 2014. Test 413 has failed. Washington D.C. is finally hit with the virus from the failed cure. But they weren't the first one. No, in fact, North America wasn't the first to get hit. No one knows who was. All they know is that the end finally came, and in the worst way possible.

This world is breaking down, and John has no idea what to do. But Dave does. Can they pull through this horror together? Will they be able to survive the horde, as well as jealousy, sorrow, and back-stabbing survivors? Or will they, too, turn into a mindless zombie?
