A/N;
Pairing: Nalu, Fairy Tail
Genre and rating: Demon!AU; T
Natsu punched the wall to his left, body shaking uncontrollably after he had run away from her apartment. He just couldn't look at her right now, her long blonde hair that framed her like a halo, her wide brown eyes that he could read so easily. Her lips that called to his or her cheeks that begged to be touched by his hands. He knew without experience that she would fit under his arm perfectly, moudling her body to his like it had been meant to be. And maybe in another life it had been, but right now it was just a cruel joke from Fate.
It wasn't fucking fair.
He was a Demon, selling his soul to the Devil to save his family, how many years ago now? 300, 400? Natsu couldn't remember anymore, but never once had he regretted his decision even as he watched so many faces come and go, souls reborn and dying again. He had borne his curse without a complaint, knowing he would have done it over again because his sister and brothers had been saved.
But now…
Now tears streamed down his face as he sank against the brick around the corner of their building. His shoulders shook as he sobbed, heart aching in his chest even if it didn't need to beat. It wasn't fair, that he had fallen in love with a Pure Soul. Even if Natsu didn't have to have his heart be broken as he watched her age and die, he knew he could never be with her. His demonic aura would taint her, and she would never be able to return to heaven.
It figured, with his luck, that he had fallen for a soul that would never be reborn, an Angel curious about humanity and risking her very place in the sky to experience life.
Natsu had never wanted to fall in love. He had never wanted anything more than to be friends with the weird blonde girl that lived in his building, laughter bubbling from her pink lips and light radiating around her so much that people couldn't help but stare and be drawn to her.
Natsu wanted to be sick.
It wasn't fair kept playing through his mind in a chant even as he buried his face in his hands and his tears caught in his white scaled scarf, the last thing he had taken from his father before he had started his wandering journey, unable to watch his family age and move on as he was trapped in a 22 year old body.
He leaned his head against the wall behind him, pink fringe invading his watery eyesight as his hair was pushed into his face. He should go back, explain to her that he had just had an anxiety attack or something. She deserved that at least. Hell, she deserved the fucking sun.
She certainty didn't deserve Natsu.
And yet she had chosen him. He felt it in what was left of his soul, the way she looked at him like he was her whole world and the soft smile she reserved for his antics when she thought he wasn't looking. But Natsu was always looking at her, even just in his peripheral.
How long had he loved her now? Natsu couldn't remember a certain point, it had probably been a gradual fall, so slow he hadn't noticed until he crashed into the rocky floor and had the wind torn from his lungs. Eyes hardening in resolve Natsu fisted at the gravel beside where he sat, blood dried on his knuckles from where he had split the skin earlier, wounds pushing the mortar and brick chips out of his body before healing.
He wouldn't leave her, not like everyone else had. Fate be dammed, Natsu wasn't about to waste the precious time he had with her, even if he could never be with her. He wouldn't steal her future from her, but he would bask in her shadow for as long as she walked the same Earth as him.
She was his Lucy, and he was damn well going to be her Natsu. An Angel had managed to steal a Demon's heart, even unaware of what she -and he- was.
It may not be fair, but Natsu had never been one to accept injustice against the ones he loved. The Devil himself could attest to that.
A.N; This was so fun to write and also super painful because Natsu angst is the best angst. Seriously tho I wanna write more of this whoops.
