While they are based off of songs, the chapters also form story arcs. The most notable of those are the "So Happy I Could Die" arc (Denmark drinks himself near to death over Norway, Norway realizes his love for him), the "Speechless" arc (the deformation of Prussia, his subsequent capture by Soviet Russia, and him reuniting with his brother Germany while finding love in Ukraine) and the Gakuen Hetalia arc.
The author wrote a follow-up, Born This Hetalian Way, for the release of Born This Way. It continues the arcs from the previous fics. There's also Hetalia's Christmas Tree, which are Christmas side stories set in the same timeline/continuum.
