You had gotten caught up in the zombie apocalypse. Unluckily for you, you got bit and had gotten infected but the thing was you weren't fully infected, you even got disgusted with yourself when getting hungry for something you usually wouldn't eat (aka humans..).

You were walking with small tremors and shakes when all of a sudden a tall obviously human guy who was Riki appeared holding a gun, a group of people also with him ready to attack/shoot.
