Great Hall, 6pm:
Scant hours before, Harry had finished telling Hermione and Ron that he was in love with Draco, and had only just now escaped from the resulting tirade—and that was only because Ron was hungry and Hermione decided to spend dinner looking up obscure spells which might have made Harry believe he was "infatuated with Malfoy."
Harry sighed, and pushed his food around on his plate. It wasn't as if he was that hungry, anyway, realizing that Draco probably didn't feel the same way about him. He looked up, hoping to catch the Slytherin's eye with his customary glare—and found Draco directing that glare not at him, but at a glass of green liquid. He left the Great Hall and headed out to the lake to think.
The Lake, 8:15 pm:
Harry had grabbed his invisibility cloak before he'd made it out to the lake—he figured that if he were out in the open, there was no way he'd be able to avoid Hermione. He'd been thinking for a while, and had resolved to at least tell Draco about his feelings for him when he saw the most peculiar sight headed towards him. Someone was dressed in all white (including a white cloak and top hat) and was running around shrieking at the top of their lungs. Upon further inspection, it was revealed that it was Draco, and that he'd painted his face white as well.
"Potter!" The apparition nearly stumbled, then appeared to regain its equilibrium.
"Potter! I –hic- I loved you! And you've killed me by not re-re- loving me back! I loved you, Potter, and now I shall haunt you and yours for the rest of –hic- e-e- for the rest of always!"
Harry couldn't believe his luck. "Malfoy, I love you back! There's no need to haunt me!"
A snort, and as Draco tried to put his hands on his hips, he fell to the ground. "As if, Potter. If you love me, why don't you –hic- prove it?"
"All right—how would I do that?"
"Kiss me." Harry was sure he was hallucinating now. "Kiss me right" –he pointed to his lips—"here."
And Harry proceeded to do as requested, which effectively shut Draco up. Seeing Hermione coming, he picked Draco up (which wasn't as hard as he thought it would be), wrapped his cloak around them both, and headed toward the Astronomy Tower.
Astronomy Tower, 8:30 pm:
Harry threw the cloak down and set Draco back on his feet. "You were saying?"
And then Draco captured Harry's lips with his own, and neither of them thought anything for the next few moments. Harry broke the kiss and started to kiss Draco's neck, and Draco started to whimper in enjoyment, when all of a sudden, Harry realized that those weren't whimpers he was hearing—they were snores. Harry sighed, pulled them both to the floor, covered them with his invisibility cloak, and decided to take a quick nap until he could put Draco to bed.
Slytherin Common Room, 11 pm:
Getting someone unconscious from the highest point in the school all the way down to the dungeons is a lot harder than I thought it was, Harry concluded as he approached the Slytherin common room. Only problem was, now he was stuck—he had no way to get Draco into the common room, because he didn't know the password. He looked around, seeing if there was someone—anyone—to help him, when he spotted someone's pet snake lying on the ground.
"Hello, little one," Harry whispered in Parseltongue to the snake.
"I am Lissssa. I belong to ssssomeone inside that room. I have never ssssssseen you before—what are you doing here?" The snake was somehow managing to look suspicious.
"I need to get him" he uncovered Draco body "back inssssside there, to his nicccce warm bed. Can you help me?"
"Yessss, I can, but only if you take me inssssssside, too."
"Of coursssssse." He held out his arm so that the snake could slither onto him.
"In that casssse, the passsssword isssss Royalty."
Harry thanked the snake and carried Draco's now-visible body through the common room and up to his dorm, where he let the snake disembark and tucked Draco in.
The next morning, when Draco got up.
Harry had spent a cramped night on the floor under his invisibility cloak, just so that he could make sure that Draco would be all right when awoke. He needn't've worried—he saw that Draco's friends cared enough to provide him with a recap of the previous night's activities. When Draco pulled his head out of the Pensieve, he uncovered himself, strode toward him, and gave him a good morning snog.
"I'm glad you got drunk, Draco, or else I would have never gotten the chance to tell you I love you." He saw Draco's face soften, and knew everything would be fine.
