The war had ended, but the casualties were still arriving.
First there was free speech. After so many years of darkness and generally horrific events, there were certain things that people just did not want to hear. So it became illegal to mention anything even slightly upsetting about the war in public. Breaking this law, that is exercising your supposed right to free speech, would cost you one month of community service; a tougher sentence than it sounded. Imagine the sort of things that have to be taken care of after a war. A war that involved magic on both sides, and specifically dark on one. Most people would prefer to act like sheep than to openly oppose this law. Then again, most people had voted for this law.
The next casualty was truth. Who cared about actual facts after a war? No one wanted to hear that it wasn't due to The-Boy-Who-Continued-To-Live-Most-Obnoxiously that the Dark Lord was defeated. What kind of a hero does a sallow-skinned, hook-nosed, greasy git of a spy make? Certainly not one that the population could rally behind and worship. So the events and facts of those war years were changed, altered. The people who knew the truth were either not believed, or too involved in their grief to notice the changes at first, and too constrained by the loss of freedom of speech that came later to comment on it.
Trust fell from the list of survivors next. During the war people trusted their loved ones. They trusted the side of good and all decisions made by those in charge of that side. Once the war ended and they saw just how many citizens amongst them had been followers of the scary bad guy, they began to doubt. And when the aforementioned greasy git of a spy was acquitted of all charges pertaining to the death of the greatest wizard of all time, Albus Dumbledore, all trust was lost. Amidst this community, the ruling handed down by the Wizengamot was no longer relevant. They could acquit all they liked; society still held you guilty and extracted its own payment for your sins.
Friendships weren't strong enough to avoid the casualty list. When two of the 'saviours of the wizarding world' uncovered the truth about how the third person of their trio was obtaining information, they didn't bother trying to save their friendship. Apparently, collaborating with Albus the Admired's killer was enough to lose someone everyone they loved. So despite all the hard work she had put in, despite everything the trio of troublemakers had gone through in their friendship, it was over. And the funny thing about this community that no longer trusted; they still trusted their heroes. And when their heroes decided to ignore someone, everyone felt it was their duty to ignore them too.
Hence the two people who had risked more than anyone else in the war found themselves ostracized by the community at large. Which might have been a good thing, considering the next casualty of peace was freedom of a different kind. On the 25 March, 2003, the Ministry of Magic passed their stupidest law yet. The Marriage Law, or Bill 5932 as it was officially called, was passed. Apparently lots of people had died during the war, and the population had fallen. For a world with as little people in it as the wizarding one, this was a serious concern. So in all their magnificent wisdom, the Ministry had now decreed that all wizards and witches must find themselves a mate within two months or face having their wands snapped.
Our two protagonists might have found this amusing, had it not affected them so badly. That the ministry would try to increase the population by threatening to remove half of it was indeed humorous to those couples who were already happily married. Not so to the greasy git and the bushy haired chit. They were single and appreciating it.
Until now.
