I also don't own Harry Potter.
Anna and Aleksandra helped me a lot with this, I love you both! Thank you!
Prologue
"Don't," crooned Moaning Myrtle's voice from one of the cubicles. "Don't... tell me what's wrong... I can help you..."
"No one can help me," said Malfoy. His whole body was shaking. "I can't do it... I can't... It won't work... and unless I do it soon... he says he'll kill me..."
"How about Professor Dumbledore, Draco? Surely he can help you," she pleaded.
"Didn't you hear a word I said? No one can help me," he let out a bitter laugh. "Especially Dumbledore, cause I have to kill him. I have to kill-" Hearing distant footsteps, Draco looked up from the sink and saw Harry's reflection in the cracked mirror. "Potter."
Harry was dumbstruck. In the six years that Harry had known the other boy, he has never seen the blonde cry. But after all, Draco Malfoy was a Slytherin. It wasn't really a surprise that Harry has never seen him cry; Malfoy always kept a mask of indifference with everyone.
"Going to speak anytime soon?"
It took a minute to register into Harry's mind that Draco had spoken. After he found his voice, Harry let go of a quiet but firm, "Malfoy," in reply.
"Still stalking me, are you? I would've thought that Dumbledore's Golden Boy had better stuff to do," Malfoy jeered. "Saving the world, maybe? Or posing for the front page of The Daily Prophet," His face was blotched in red and had a slight sheen of sweat, tears, and water, and his usual silver blue eyes were now a cold hard titanium, with a dark shadow looming over them.
"Malfoy..."
"I don't want your pity, Potter!" The shout reverberated in the small bathroom. Malfoy raised his wand, which was in danger of falling onto the floor due to the intense shaking of the hand holding it, and shouted a jinx at the dark-haired boy.
"Reducto!"
"STOP IT! ST-" Moaning Myrtle was screaming bloody murder as she flew out of the bathroom as her cries were ignored by the two boys."HELP! HELP!"
Harry quickly jumped to his right and landed on his stomach, narrowly avoiding the curse. A light spray of water notified Harry that Draco's jinx hit a sink instead, blowing the water pipe. Malfoy threw another curse to which Harry quickly rolled away from and the poorly aimed curse resulted in a heavier flow of water spilling from the damaged sink.
Although Harry knew that Malfoy was going to fire a new curse in his direction, he didn't make any motion to take out his own wand. And as expected, a sharp pain in his side told him that Malfoy's new curse didn't miss its intended target.
There was a dull thud of Harry's knees and hands hitting the tiles as the effort to breathe was becoming more labored. His field of vision was tinged pink and was slowly narrowing to a focal point.
Harry attempted to get the room to stop spinning but he couldn't. Then, he pushed up onto his feet with great difficulty with the small bathroom threatening to collapse on top of him as he staggered toward the shaking blonde. Struggling to hold his head up, he directed his green eyes to look into the gray ones. Malfoy's eyes were shining with unshed tears and flashed hurt and concern when his eyes connected with the other boy's.
"Draco..."
With the last of his strength, Harry staggered the last couple feet into Draco's arms. Suddenly, warmth covered his own cold lips. Then, a single tear slipped out of his eyes, slid down his cheeks, and mingled with the joined lips below. And right before he was engulfed in the lonely darkness, Harry's last memory was of Draco's voice whispering, "I'm sorry..." into his ear over and over again.
