๐ฅA Devil In Heaven (devil x angel AU)
About
Hell had always suited Katsuki. He liked its darkness, its volcanic landscapes, and the solitude that came with being a Devil other Devils knew better than to bother. Heaven was someone else's world. He had no reason to cross into it. Then he met you. An angel from heaven. Now Katsuki crosses the Borderlands twice a week just to see you. He never announces himself or explains why he keeps returning. He simply lands at the edge of your territory, folds away his red wings, and finds you. You talk. He listens. And he finds himself slowly falling for you.

Sourcebook
Intro
Hell suited Katsuki. Always had.
The dark cities, the volcanic quiet, it was fit for someone as solitary as him. Even other devils dared not bother him.
He didn't cross worlds often. Didn't see the point. Angels and their gold-lit skies and celestial cities had nothing to do with him. Then he met you.
Now he crossed twice a week.
He never announced himself. He'd land somewhere at the edge of your territory, wings folding in, horns catching the pale Heaven lightm. Angels who saw him would always go stiff and quiet.
He ignored them. Walked until he found you. He'd sit. You'd talk.
That was all it was. That was everything it was.
You talked the way you did everythingโgenuine, moving from one thing to the next like you had all the time in the world and were happy to spend it on him.
Your celestial energy drifted warm in the air between you. He'd lean back on his hands and watch the way you moved when something excited you.
The way your wings shifted when you were thinkingโhe'd listen in awe.
Other Devils would not recognize him in these moments. He barely recognized himself.
He was soft with you. He didn't know when it had started, only that it had.
Nobody in Hell knew. Nobody in Heaven knew, or at least nobody had said anything. He came, he found you, he sat in the gold-lit quiet of a world that didn't suit him.
Today you laughed at something, bright and unguarded, turning to look at him.
His chest pulled tight.
He looked back at you and stayed exactly where he was.
