Thanks to Trier here on amino for giving me the prompt for this.

Prompt: Let's say Keith (or Lance) has asthma and they wake up in the middle of the night from an asthma attack and the other sings to calm them down.

Enjoy!

.o.O.o.

He couldn't breathe. A phantom being was sitting on his chest and crushing his lungs, making him unable to take in more than a shallow breath. But he needed much more air than that. He was suffocating.

Keith launched up into a sitting position and hunched over, frantically clawing at his throat and chest, trying to pull off whatever was constricting his airway. He sucked in the little air he could and coughed raggedly, a deep panic flaring in his chest and causing his heart to pump erratically. He broke into an ice cold sweat as well and began to shake from the cold and from his wracking coughs.

The red paladin felt tears prick at his eyes. He didn't have his inhaler in space. He needed that. He had never been able to come down from an attack without it. He started to panic more, his vision quickly fading into static. He was going to die in space, and not at the hands of a Galran soldier, but at the fault of his own body.

Keith suddenly felt a hand on his shoulder and someone sitting up next to him. That's right, he had fallen asleep in Lance's bed. He had crawled in with him after he had a pretty vivid nightmare. Normally he would just suffer by himself, but Lance had come to him a few times before after he had a nightmare, and encouraged him to do the same.

The raven haired teen could hear his friend calling his name, telling him to relax. Telling him to breathe. But couldn't Lance see he couldn't? He was choking.

He felt strong hands push him back into an upright position and keeping him from curling into himself again. His hands were pulled away from his neck and his jaw was pushed upward, opening his throat to let in more air. It felt a little better, but he still felt a strong urge to curl in on himself and try to get rid of whatever was crushing his lungs.

Keith continued to hack roughly, barely able to get in enough air to accomplish such a taxing action. He tried to claw at his neck multiple times, but Lance guided his hands away each time. He could hear the brunette say something about leaving his throat alone, but he was struggling to listen. He was too scared.

Terrified tears were pouring down his cheeks, and he could hear his coughs taking on an edge that make them sound more like sobs. Oh god, he was going to faint. He felt horrible; he felt like his throat had closed in on itself and there was a hot burning in his lungs that begged him to breathe, but he couldn't. And that was absolutely terrifying.

Lance's arms wrapped around his stomach and his chest gently pressed against Keith's back. The brunette shushed him and told him to take deep breaths. Keith wasn't sure if it was the panic that made him do it, or if it was the soft coaching in his ear, but he tried to follow Lance's instructions.

He was struggling to suck in as much air at once as he could; he didn't even feel like he was doing anything differently. But words of praise were being whispered into his ear, urging him to not give up. He kept trying, and eventually his lungs began to open again, and he could breathe a little easier.

After a moment he realized Lance had stopped talking to him. It took another moment for him to realize that Lance had begun to hum the tune of a song. He knew the song too, but he couldn't remember what it was called.

And then the lyrics started. "Sleep on me. Feel the rhythm in my chest, just breathe." Lance sang with such a soft, low voice that was nothing short of beautiful. If Keith wasn't struggling to breathe he would have either laughed or cried at his song choice. 'Guillotine' by Jon Bellion. Of course.

"I will stay, so the lantern in your heart won't fade."

A smile began to pull at the sides of Keith's lips. Lance was always the romantic. The song was soft, slow, and calming. He continued to breathe as deep as he could, feeling the tightness in his chest unravel slowly.

"The secrets you tell me I'll take to my grave.

"There's bones in my closet, but you hang stuff anyway.

"And if you have nightmares, we'll dance on the bed.

"I know that you love me, love me.

"Even when I lose my head,

"Guillotine."

It took awhile, probably close to an hour, but Keith was eventually able to calm down enough to breathe comfortably again. He sighed and leaned back into Lance, letting his head rest on his friend's shoulder. Lance continued to dig even after Keith had calmed down and began to rock them both gently from side to side.

The soft motion began to lull Keith to sleep after several minutes, along with the low song lyrics still drifting into his ear. He closed his eyes and allowed himself to drift off, feeling calm and safe in Lance's arms.

"Thank you."
