Sorry to butt in
Haikus are about two things
Please read haiku link:

"Traditionally and ideally, a haiku presents a pair of contrasting images, one suggestive of time and place, the other a vivid but fleeting observation. Working together, they evoke mood and emotion. The poet does not comment on the connection but leaves the synthesis of the two images for the reader to perceive."
