Disclaimer: I don't own Harry Potter.
Harry stood beside the stands of the Quidditch pitch under his invisibility cloak, racked with nerves. If they lost, the setting would be ruined and he could breathe easier but if they won, he would have to go through with it. He watched his girlfriend fly and a wry grin crossed his face. There was no way they would lose. Ginny. His beautiful, strong, powerful, funny Ginny. She was his salvation, the last thing he thought of before he had died that night in the Forbidden Forest. Gryffindor's seeker caught the snitch as they won the house cup and he swallowed hard, summoning all of his courage. He had arranged with Demelza (one of the other chasers on the team) to keep Ginny in the middle of the field once everyone else had left.
He tugged on the collar of his old school robes as he waited for the stands to clear out. Finally they did and he threw off the cloak and enlarged the guitar he had brought with him. He muttered a prayer to the sky and made his way out to her. "Harry! Wha..." He made a shushing motion and she shut her mouth, puzzled, as she eyed the guitar on his hip. He cleared his throat. "I have a speech so please don't interrupt or I might not make it through." She nodded, a little nervous herself now.
"Ginny. You were the spark of hope in my chest that kept me alive in the darkest times. You loved me for me, not the fairy-tale vision of me. You aren't perfect but that's what makes you perfect. Your eyes may not look like fresh pickled toads, no." She let out a choked giggle. "They look like home. You are the most beautiful girl that I have ever seen from your long red hair down to your toes. You save me every day and I could never thank you enough for that. I love you more than words could ever express so I learned how to play a song so I could sing it to you." She raised her eyebrows at that and he hoped that Hermione hadn't been lying when she told him that he sounded good.
"You and your stained glass windows, me and my cracked windshield, you and your quiet view, me and my can't sit still" He watched her assessing him and breathed a little when he saw her smiling, love in her eyes. He felt entirely vulnerable as he started the chorus. "Cause I'm hell up here on the high wire, you're the Hallelujah kind, I'm the dust that spins and the gust of wind that's blowing by, I'm a desert dry, and in my thirsty eyes, you look like rain, you're my sweet rain."
There were tears sparkling in her eyes and he abandoned the guitar and let it fall to the ground as he pulled the jewelry box out of his pocket. "Ginevra Molly Weasley, will you make me the happiest man alive? Wil you marry me?" For a fraction of a section she stared at him, mouth agape. Then that blazing look he had come to love crossed her face. "Yes." A smile split across his face so wide he thought it might break. He slipped the ring onto her finger and she threw her arms around him and all he knew was her lips.
After what felt like several sunlit days they broke apart. "Harry Potter have I ever told you how much I love you?" He smiled softly down at her. "A couple of times." He gave her a sly look. "Did you like how I incorporated fresh pickled toads since" He smiled against her mouth as she cut him off with a kiss. She was definitely the Hallelujah kind.
