Eh, the only thing I have to say about your A/N is that, we really don't know what happened in those two decades between DH and the prologue. All we know is that Harry a Harry and his wife sent off their kids, and met up with his friends and saw an old enemy. We don't know what changes were made in the wizarding world or not. We don't know what the Malfoy family went through in order to stay in Britain or if they went through anything at all. Apparently their values as a pureblood family did not change, but you can't change values, can struggle to change beliefs, but you can change habits. I like to think that the Malfoys actually did go through crap at the end of the war, simply because they were still alive. Sure, they saved Harry's life twice, but that doesn't count for the dozen times they tried to end it, or the crimes that Lucius committed. Draco had to answer to his own choices, as did Lucius and Narcissa.
And I'm nearly certain that Hermione, Harry, and Kingsley would not have let the Ministry continue as it had.
Otherwise, I rather liked this story. I liked the twist on Luna, and this version of Harry's "harem" since normally he has Hermione, Ginny, and Luna, with one or two other girls. I'm a Harmony fan myself, so I appreciate any story with the two of them, but adding Padma and even Myrtle were nice twists ^_^
