I don't own Naruto.
The girl in the story doesn't have a name, so just make it up or something :P
Gaara is still awake, sitting at her desk. He takes her craft knife and cuts his finger open. He lets it run, just watching it, and then he tastes it, remembering the time when his uncle had put his cut finger in his mouth.
She wakes up and sees him sitting there with his injured finger.
"Gaara, why did you do that?!" She grabs a shirt from the floor and wipes off the blood, then digs around in her desk for a band-aid.
"The sand can't protect me when I'm here."
"That doesn't mean you should hurt yourself!"
"Did you know that I've only felt physical pain a few times in my life?"
She didn't answer, but she knew. She also knew that he had suffered so much emotional pain that it was a wonder that he hadn't killed himself—but the sand had also kept him from doing that for thirteen years.
Gaara took her hand picked up the knife.
"Gaara, what—" He cut her finger with the knife. "Ouch."
She was about to pull her hand away but he put her injured finger in his mouth.
Her mind momentarily flashed back to a scene she had seen of him and his uncle when he had tried to explain pain to a six-year-old Gaara. It was the first time he had ever tasted blood, never being injured before.
"Your blood tastes just like mine." He let her hand go. She wiped off the blood and put on a band-aid.
"Of course it does," she smiles at him, "why wouldn't it?"
Gaara looks away. "Because I'm a monster."
She puts a hand on his cheek, turning him back to face her. "Gaara, I don't care if there is a demon inside of you," He looks into her eyes. "So long as you're you, I'll always love you."
His eyes begin to fill with tears.
"I'll always stay by your side."
"Always?"
"Yes, always." She kissed him.
