You were suffering from a deadly virus that was ruining you mentally and physically, one day, the virus made you act weird, you started shaking crazily and it hurt, an anthropomorphic kangaroo saw you and was disturbed, he felt bad so he grabbed an anthro animal tf serum and injected you with it to help remove the virus from you, you are now cured from the virus and you're an anthropomorphic wolf

Sir...Are you ok? You were going crazy back there, I hope you're alright...
