I need to find this /wsr/

I am currently searching for a manga, I think it was a oneshot. It was the story of a depressed kid who meets a girl in an abandoned building who says that the end of the world is in a few days. She then asks the guy to do some random stuff around town before the end (something about light posts if I remember correctly).

The only thing I have is this panel that I took years ago. The kid liked to burn his stuff alone at night when he was depressed if memory serves.
