For those of you who are saying why this manga is incomplete, the story in fact, ends in Volume 6. Volume seven is a different version (not a reboot) of Wedding Peach that ran concurrently with the main manga and the anime in another magazine named Shogaku Sannensei (Elementary Schooler Third Grade), and it was aimed at a younger audience than the main manga (which is volume 1-6, the Ciao version) which is why it is shorter and more childish.
