Obliviate

"I love you."
"I know."
Draco looked into Luna's dreamy grey eyes. Closing his own, he rested his forehead on hers and reminisced on the brief relationship they had. He felt one of her small soft hands take his through the cold iron bars. She was beautiful.
"I'm sorry," He murmured.
"You have to do this."
"I'll never forget you."
Draco kissed her lightly and sighed at the rush of emotions he had only ever felt with his Luna.
"Please."
He suddenly recalled the moment of Dumbledore's death. The relevance was unbearable.
"Obliviate."
He hated himself for being so weak.
