These ideas have been floating around in my mind for a while. If there is any pairing you'd really like to see, send me a request in a review, otherwise, I'll just write about whoever comes to mind next.
Notes: This takes place about 5 years after the Battle of Hogwarts. Harry is Head of the Auror Department. Ginny has recently been proclaimed Captain of the Hollyhead Harpies because the previous captain had a career changing accident. During her first year as Captain, she managed to convince Angelina Johnson to join the team as well.
Harry had been planning this for several months. As soon as he heard that the Quidditch World Cup would be held in England again. Things worked out even better than he had expected when the Hollyhead Harpies actually made it to the world cup. Harry had high hopes for the game. They would be playing against Italians, but Ginny had put together, and trained, a great team. He had gotten his presentation of the Cup approved by Minister Shacklebolt (no surprises there). He bought the ring a week ago. It was a five carat diamond in white gold.
Harry was, of course provided a seat in the top box, one of the perks of having defeated Voldemort. Ron and Hermione had asked to be there, so Harry secured seats for them in the top box as well. They had all met at Harry's campsite last night, but Ginny had left early in the morning to prepare for the game. The Golden Trio was now seated in the top box, watching as the teams were announced. The game was exciting. Ginny and Angelina scored so many goals, that there was no way the Italians would ever catch up. It helped that they had an excellent Keeper. Finally, after two hours ad a score of 500-90, the Harpies' Seeker caught the snitch.
The crowd went wild. For the first time in fifty years, England had won the cup. The Harpies took their victory lap as the Italians came up to the top box to meet the English Minister of Magic. The top box was now magically lit up, so everyone could see. Per Harry's request, and Hermione's research, they'd also found a way to project what was happening in the top box to giant screens around the stadium, just like a muggle television. Harry's heart started pounding as the victorious team made their way into the top box. Minister Shacklebolt handed Harry the cup.
"This year, Harry Potter, The Chosen One, requested to award the cup. I hope you pardon my indulgence in acquiescing." Harry mentally rolled his eyes at the Minister's words, but acknowledged the brilliance of them. After all, who would deny 'The Chosen One'? Harry magically enhanced his voice, lifted the Quidditch Cup, and spoke.
"On behalf of the Minister of Magic, I, Harry Potter, do hereby present the Hollyhead Harpies with the Quidditch World Cup." He handed the cup to Ginny, who, as he had expected, passed it to her teammates to admire. Before she had turned back to face him, Harry pulled the box out of his pocket and knelt. Angelina noticed first. She squealed in delight and pointed. Ginny spun back around to face Harry, eyes wide. An eerie silence settled over the stadium as everyone took in what was happening.
"Ginerva Molly Weasley, you are, without a doubt, the most amazing woman in the world in my eyes. You kept me grounded when we were fighting in the war. You brought me happiness in the aftermath, when I thought there was none to be found. I love you, Ginny, and I want to spend the rest of my life with you. Will you make me the happiest, and luckiest, man in the world? Will you spend the rest of your life with me as my wife?" Ginny stared at Harry for a moment, her eyes sparkling with tears, then she launched herself at him, shouting, 'Yes!' over and over again. The entire stadium burst into applause. They could hear catcalls, and hoots.
When Harry was able to extricate himself from her embrace, he took the ring out of the box, and placed it on her finger. It glowed brightly for a moment, then magically resized itself to fit perfectly. Harry removed the enhancement of his voice, then turned to Ginny.
"I love you, Ginny."
"I love you too, Harry. This day can't get any better. First we win the Quidditch World Cup, then I get engaged. This was amazing, I can't believe you planned it all out."
"All for you, Ginny." She smiled and hugged him close. Harry smiled. The day had gone exactly according to plan.
