I didn’t understand this. I’m sorry, would appreciate if you do explain.

Wow, sorry it came out weirder than I thought it would, There are supposed to be spaces in between the words.. but yes, I can do my best to explain it, Truthfully when writing Haiku’s I mainly think of one syllable words that are in my head or happening to me at the exact moment, I put them down on a peice of paper and try to make them work together. This particular one means that the small fiend that is delivering is delivering a virus, a sickness among the world, the pianists intensify because in things like movies when bad things are about to happen the piano will get louder, it will intensify. and Sly, because this cloud of sickness comes in quickly, yet may never leave. I think I might not have wrote it according to the original Haiku style though.
