Harry Potter and the Deathly Hallows, Chapter 36, Page 597 -
"There would be time to talk later, hours and days and maybe years in which to talk."
Harry doesn't want to talk about their relationship; doesn't mean to imply that they will be together in years to come. He hopes they will have years in which to talk; he hopes that they will still be friends for years, even after he explains to Ginny that the can't be together. Not, this time, because of the threat of Voldemort or even because of the pressures of being The Boy-Who-Lived, but because he's had time to think in those months spent away from her. He's had time to think and time to realize a few things about himself, had time to realize that he and Ginny are never going to work out.
So later that morning, having had a little time to himself for the first time in what feels like an age, Harry sits Ginny down, away from the hustle and bustle of the clean-up crew currently working to restore the castle, and explains to her that he loves her. He always has and he always will. That hasn't changed. What has changed is the way that he loves her; he loves her the way he loves Ron and Hermione and all of the other Weasleys: she's - they're - the family he never had. He loves her like a sister and always has, he realizes. He expects her to be angry, is ready for the imminent explosion, but she just gives him a watery smile and a kiss on the cheek and tells him she knew it was too good to be true - they'll still be friends and she'll always love him, no matter what.
The Great Hall is in much better condition now than earlier that morning; the rubble's been cleared away, the tables are buzzing with students and someone's fixed that one broken window.
The Gryffindor table is packed with students of all houses, crowding around Neville and Seamus and the others, who have been declared war heroes.
The Hufflepuff and Ravenclaw tables are quieter, mostly occupied by Hogsmeade residents and Order members, but it's the Slytherin table that really stands out.
Three people sit huddled together at one end, looking quite out of place; two of them in Death Eater robes, the other in singed school ones, the green and silver lining barely visible beneath layers of dust and ash. The rest of the table is quite deserted.
Harry sits down opposite them, smiling weakly at their shocked expressions. He's not sure he'll ever be able to than Narcissa enough but he certainly tries. He knows she only saved him to save her own son but it means a lot nonetheless.
Draco isn't too impressed by Harry's show of gratitude and Harry finds it oddly comforting - at least something hasn't changed.
The two spend a lot of time together over the next few days, to his friends' utter disbelief. No-one else seems to notice.
Harry testifies at the Malfoys' trial, though he can't quite save Lucius from a brief spell in Azkaban. Draco doesn't blame him. In fact, if Harry didn't know any better, he'd say Draco was thankful for the time away from his father.
Harry and Draco grow ever more closer now that the war is over. And if the Prophet occasionally comments on their 'blossoming relationship'? - well, hey, they need something to write about now old Voldy's gone.
