A/N: I don't own the Potterverse, JK does. I just play around in the sandbox she built for us.

There were many houses across Great Britain, but this one was hers. It was different. Here, she belonged. Here, she felt like a real person, with real ideas, real feelings, not just a sideshow attraction to be stared at and ridiculed. It could never truly replace the home she had lost during the war, but she had put a lot of time and effort into making it something she loved, and it showed in every facet of the house. There were no perfect right angles to be found in this house; everything about it was just slightly off, but not so much that most realized it was even designed that way. That was a nod to her tormentors, who believed there to be something very off with her. She delighted in tweaking their noses in that subtle manner; not that any of them would dare to come inside her home, nor would they be invited in should they brave the visit.
Thanks to her family, she could easily afford to build her dream home. While the war had taken them away much as it had her home, she had found a loving group of friends during her years at Hogwarts, and they had helped her move on from the darkness in her past. It was said that the houses had not been so united as they were by her graduation since the time of her grandparents, and not since the founding of the school had the greatest of rivals, Gryffindor and Slytherin, been on such friendly terms. She was a large part of that; she, and her "study group", who in seven years did much more together than merely study the subjects taught at Hogwarts School.
Though she had at times entertained leaving the Isles all together, and finding a new place to build a new life, she felt as though she was tied to the land. Not literally, of course, and not bound by magic in some way, but instead as though she was one with Britain itself. Building her home solidified her ties; preparing to have a real family here with her girlfriend was just the next logical step in that process.
Of course, she had taken the time to make sure her friends saw things the way she did. Ron and Tracey, the Golden Couple that had finally reunited Gryffindor and Slytherin, were ecstatic for her. Cho, her longtime rival and confidant, was honored to have been told before the event, and promised to help with the nuptials however she could. Hermione, the one who knew her best, just gave her a big hug. Neville and Ginny remarked on how the pair just seemed perfect for each other, as they themselves had been told many a time. Terry, who'd introduced them in the first place, humbly asked that he be given all the credit for making it happen, and received a smack in the shoulder for his troubles. Susan and Hannah offered up their coffee shop as a place to come celebrate afterwards, and promised to have treacle tart ready for both of them. All that was left was to go tell the one herself.
She Apparated over to the Rookery, a very homey building in its own right. It had definitely seen better days, but Luna had done a good job in keeping it together, as much as any one witch could. She only hoped that the offer she was about to make would be enough to convince her that it was time to let the old house go.
Inside, Luna sat, idly sipping a cup of tea and wondering why her girlfriend was so late. "Finally," she thought, as a knock came at the door. "I was beginning to wonder if Blackbird had forgotten completely." While the rest of the world knew her girlfriend by a different name, Luna had insisted on calling her Blackbird for a week after she decided to dye red streaks in her jet black hair, and the pet name had persisted to the present day, though it had mostly faded behind closed doors.
She opened the door, and immediately threw her hands over her mouth in surprise. There, on her doorstep, kneeling while offering up a beautiful ring, was her Blackbird: Harriet Lily Potter. As with many conversations between the two, no words were actually spoken. None were needed. Luna carefully extended her hand, and the ring slid perfectly into place. She helped Harri to her feet, and fell into a warm, loving embrace.
"I'll ask about the house later," thought Harri.
