Some old AU snippet where Tae has healing powers that make him run hot all the time.
"No", Taehyung whispered. He brushed his shaking hands down the length of Jeongguk's bloodstained face. "No, no, no."
"Not like this, Guk-ah," Taehyung stammered, more to himself than the unconscious boy in his arms. He tried to stop the tremors wracking him but it was impossible. He shivered again and bent down, pressing his trembling lips against the locks of hair on Jeongguk's forehead. Jeongguk's skin was cool to touch. "Not today."
Heal.
The tell-tale heat coursed through his veins. He felt it, from its inception in his heart to its end at his fingertips where they were pressed against Jeongguk's pale skin.
Already, Jeongguk looked better. A little colour in his cheeks, a deeper rising and falling of his chest. But Taehyung knew it would take much more for the wounds to be fixed properly and permanently. Jeongguk's wounds were mortal wounds after all. Enough to take a person's life, to rip up the roots of the soul.
If Taehyung stopped now, all he would be doing would be easing Jeongguk's passing.
Unacceptable.
Taehyung gritted his teeth. His mother's face appeared in his mind, unbidden, and he apologised silently for not being able to see her one last time. Then he gathered himself, and looked up at the Seoul sky.
The rain had ended and it looked like the clouds were passing, the sun just peeking out.
Life.
It burned. Taehyung had never felt his power burn like this before. It was fire, in his chest, and he screamed in agony as it made its way down his arms and to his fingers.
The pain seemed to go on for an eternity, pulses of fire tracking through his veins.
And then as suddenly as the pain had started, it ended. In his arms, Jeongguk coughed and let out a wet gurgle. The sounds came from very far away, like Taehyung was hearing them through a tunnel, but the relief that spread through Taehyung was there all the same.
"T-tae?" Jeongguk asked, his voice cracking. His face was turned up into Taehyung's, big eyes confused. "Where – what are you- "
Taehyung saw the second Jeongguk remembered and the boy shot upright, patting himself in the stomach.
"I got shot, what the hell, what – " Jeongguk patted himself increasingly vigorously, his hands coming back tacky with his own drying blood. He pulled his shirt up, smearing the blood on his stomach aside, searching for the wounds. "What the fuck?"
Taehyung felt cold and a little bit vague. He had never felt the cold before and it was an unpleasant sensation. He couldn't say that he recommended it. The shaking of his limbs was getting uncontrollable now and it was getting tedious to hold himself up.
"Taehyung," Jeongguk breathed out. He pulled off Taehyung like Taehyung burned, when it was really quite the opposite. "Tae, what did you do?" His voice had a tinny, faded quality, like old recordings and black and white movies, and sounded like it was coming from a great distance away.
A nap would probably be a good idea; no, a great idea. If Taehyung could just shut his eyes and lay down, just for a second – he would probably be okay.
As Taehyung lay down to take that nap, he idly wondered if Jeongguk would have made a good silent movie star – he probably would have. Jeongguk had the kind of striking good looks required. He was very expressive, very good at projecting emotions – the way he was crying now, fat tears rolling down his cheeks and his mouth moving like he was sobbing and shouting – Taehyung had no doubt his Jeonggukkie would've been a star.
