It'd been a few months since the apocalypse had started, all coming from one person who passed it on to another, and so on.

The victim starts growing flowers on their body, causing them to get similar symptoms to a fever or the flu yet more severe before eventually killing them.

You'd been isolated in your apartment, baracading all doors and staying up on a high enough floor so the gas couldn't reach.

After a while of not being able to do anything but stare at your roommate's dead corpse, covered in those pink flowers, and realizing you were running out of food, you decided to go out, putting on a gas mask as you went on a search for supplies.

On your way there, you spotted a familiar trenchcoat, worn by none other than your friend Constantine.

He didn't notice you, still roaming around the streets as if the apocalypse had never happened.
